Data Connections

Data commands apply to the setting up, configuring, and statistical reporting for data connections. The nodes and card sets to which the commands in this chapter apply are:

For descriptions of commands that apply to data connections on a FastPAD, refer to the FastPAD User's Guide.

Examples of the tasks described in the chapter are:


Setting Up a Data Connection

To set up a data connection:

Step 1 Configure the data channel at each end of the connection. The format of a data channel designation is slot.port. For example, 6.3 is port 3 on card slot 6. The items that need configuring depend on the type of data connection. The configurable parameters and their associated commands are as follows.

· cnfdclk Specifies the clocking for the data channel
· cnfcldir Sets the control leads for bidirectional pins 11 and 23 on an RS-232 data channel. The default is input
· tstport Use sixth lead feature to provide test port loopback
· addyred Enables redundancy for a data circuit or port. This step is optional
· cnfict Configures an interface control template that determines output lead behavior for data channels. Output leads can be either configured as steady state (on or off) or programmed to follow an input lead. Five types of templates exist for channels in active, conditioned, looped, near, and far states.
· cpyict Copies interface control template information from one channel to another. This step is optional.

Step 2 Add the connection with the addcon command. The above configuration must have been completed at each end before the connection can be added.


Configuring Data Channel Redundancy

Data channels can be configured for redundancy by installing two identical sets of data front and back card pairs in adjacent slots and connecting to the customer's line through a Y-cable.

  1. Use the addyred command to establish the redundant connection between the two card sets.

  2. Use the delyred command to remove redundancy from a redundant pair.


Using an Interface Control Template

Data channels have an associated default interface control template for each of the active (normal), conditioned, looped, near and far states. The templates define how the control leads at the data interface are to be configured (asserted, inhibited, follow a local source or follow a remote source). The interface control template can be changed by using the cnfict command. Each template and each control lead must be configured individually. The cpyict (copy interface control panel) can be used to apply (copy) the settings of a template for one data channel to those of a template for another data channel.


Enabling DFM and Data Channel Utilization

DFM (Data Frame Multiplexing) is a feature on the IPX and IGX in which repetitive data patterns (such as IDLE codes) are suppressed at the source and regenerated at the remote node. This feature is transparent to the user and has the effect of approximately doubling the bandwidth of the data channel.

To enable DFM at one or more nodes of the network, ensure that the DFM feature has been ordered and call the StrataCom International Support Center (ISC). When the selected nodes have DFM enabled, the user may disable/enable DFM and change the DFM values at these nodes on a channel-by-channel basis with the cnfchdfm command. (When DFM is first enabled at a node by ISC, each data channel has the following DFM default values: percent utilization of 100%, pattern length of 8 bits, and DFM status "enabled.") The DFM settings for a channel can be checked using the dspchcnf command.


Enabling Embedded EIA Operation on the LDP

The EIA feature encodes the status of the CTS or RTS lead as the eighth bit in each data byte. Then the byte is processed in accordance with the DFM algorithm, which remains unchanged.

Any combination of DCE and DTE at each end can be valid. A typical configuration might have the LDP one of the connection as DCE (normal clocking), and the LDP at the remote end as DTE (looped clocking). RTS is transmitted in encoded form from the remote end to the host end, and CTS in the other direction. Other EIA leads will use the non-interleaved format.

The EIA feature is allowed for all legal baud rates 19.2 kbps and below and is activated by typing encoding type 7/8E followed by an *Z when adding a connection using the addcon command. Different channels on the same card may be set up with or without the feature, but all ports on the card must be configured at or below 19.2 kbps for EIA to be active. Note that you do not have to enter *Z after 7/8E on the command line because the system automatically enters it.


Setting Up DDS Trunks

DDS Trunks normally operate at 56 Kbps. The IPX and IGX can provide a direct interface to a DDS line and provide limited distance access to Data Service Units (DSUs) by using the DDS format over private lines. The LDI4/DDS back card and LDP (Model B) or LDM front card support DDS accomplished using the and . Each LDI/DDS supports four DDS trunks in DSU or OCU modes.

Configure the Interface Control Template for node alpha port 18.1 using the cnfict command. The Interface Control Template for Connection while active should have the DSR, DCD and the CTS lead ON. If any of these leads are OFF, perform the following using the lead signal name (DSR, DCD, or CTS).

addcon

Establishes the channel connections between nodes in the network. After a connection is added with the addcon command, the connection is routed automatically by the system. The node where the addcon command is entered is considered the "owner" of the added connections. The concept of ownership is important because automatic rerouting and preferred routing information for a connection must be entered from the node that owns the connection. See the cnfpref and cnfcos commands for more information on automatic rerouting. Before a connection is added, the proposed connection appears on the screen and you are asked to confirm the addition.

This form of the addcon command is used to add a synchronous data connection to the network. It can be added to any node slot equipped with either an LDP or SDP card in an IPX or an LDM or HDM in an IGX. Before adding the connection, determine a data rate to us. Refer to the card descriptions in Chapter 1 of either the IPX Reference Manual or any of the IGX reference manuals to determine the data rates supported by the different models of these data cards.

When connecting sets of data channels, you do not have to specify the full channel set for this end of the connection. You only have to designate the first channel in the set. For example, to connect channels 27.1-4 at alpha to channels 9.1-4 at beta, you could enter "addcon 27.1-4 beta 9.1". When Y-cable redundancy is being used, you can only terminate data connections at primary card slots, not at secondary (redundant) card slots. See the addyred command for more information. Data connection rates follow. When reviewing the connection rates, please note the following:

· * must be used with 8/8 or 8/8I coding.
· /n specifies a partially filled packet type. This allows lower rate packets to be sent without incurring the delay required to build a full packet
· f entered after the data rate specifies "fast EIA" (interleaved EIA) for the data connection.
· t indicates transparent (CDP or CVM subrate DS0A). The IPX and IGX do not look for supervisory or control information.

In "fast EIA" signalling mode, an interleaved byte of EIA signalling information is associated with every byte of data transmitted in a packet. This format is appropriate for applications where EIA lead transitions must be closely synchronized with user data. Fast EIA is usable for data rates up to 512 Kbps.

With the 7/8 coding format, the user's data is received, and 7 bits at a time are used to form bytes in a packet. The user's data can be any format and can contain any pattern including all "0"s. The single "1" inserted in the final bit position ensures that no more than seven "0"s will occur consecutively in a byte. This is the safest mode to use if the data protocol is unknown.

With the 8/8 coding format, the user's data is received and a full 8 bits are used to form bytes in a packet. The coding format is more efficient than the 7/8 format, but the end equipment is responsible for meeting the T1 transmission requirement of no more that seven consecutive "0"s in a byte. If this requirement is not met, the IPX or IGX inserts a "1" to invalidate the data. This mode can be used if the data or transmission line protocol avoids long strings of zeros, e.g., T1 trunks that use B8ZS encoding.

With the 8/8I coding format, the user's data is received and a full 8 bits are used to form bytes in a packet. The data is inverted so that "1"s are changed to "0"s, and vice versa. The end equipment must guard against data that contains over seven consecutive "1"s in a byte, which (when inverted) would violate the T1 transmission requirement. This would cause the IPX or IGX to insert a "1" to invalidate the data. This format can be used for data protocols in which the idle codes are long strings of 0s and the data bytes scrambled.

If the data protocol requires an acknowledgment and is delay-sensitive avoid routing the connection over a satellite line (*s for avoid). If 8/8 or 8/8I coding is the selected format, StrataCom suggests avoiding the use of trunks with zero code suppression (*z for avoid) because it could corrupt the last bit in the byte.

Parameter Description
avoid Specifies the type of trunk for the connection to avoid. The default is no avoidance. The choices are:
*s avoid satellite trunks.
*t avoid terrestrial trunks.
*z avoid trunks using zero code suppression techniques that modify any bit position to prevent long strings of zeros.


cnfchdfm

Enables DFM for individual channels and sets the DFM parameters for the channels. The DFM feature must be installed in software at each node terminating the connection. If DFM is not installed for a pertinent node in the network, the channel-specific DFM disable/enable command (cnfchdfm) has no effect at that node. For a data connection to use DFM, both ends must have DFM enabled with the cnfchdfm command. Also, an SDP Model B or later or an LDP or CDP in an IPX is required at both ends of the connection. In an IGX, both ends of the connection require an LDM, HDM, or CVM. The cnfchdfm command must be used at both end-points of the connection.

cnfcheia

Sets the sampling rate for the updating EIA control leads. This rate can be set from 0 (no sampling) to 20 updates per second and defaults to 2 seconds. This rate governs the polling interval and packet generation rate for the EIA leads associated with the channel.

At 20 updates/sec, the control leads are polled for changes every 50 msec. Therefore, changes occurring more rapidly than that may not be detected. If there is no change in EIA lead status, no packet is sent. A minimum of one update per second is sent if the maximum update rate chosen is from 1 to 20. If the connection is configured in such a way that an implied isochronous clock is detected, the update rate is always 20/sec in the same direction as that of the clock signal. For 1.544 Mbps data connections, this defaults to 0.

Sets the control lead direction for pins 11 and 23 on the RS-232 data channels of an SDP or HDM card set. This allows the control leads to carry "backward" channels. Pins 11 and 23 on an RS-232 interface are bi-directional. The signals on these pins can have various names, such as SI, SF, CH, CI, and QM. To display control lead information about pins 11 and 23, use the dspbob command. Use the cnfict command to configure the behavior of all output leads.

cnfdchtp

Configures a CDP, CVM, or LDP or LDM DDS port interface type to OCU or DSU. When configuring DDS operations, this command returns an error if executed on a slot with an RS-232 back card. It forces a back card slot from RS-232 mode to DDS mode if a back card is not installed and there are no connections. Any Y-cable association is deleted in this case. The clocking tracks the DDS port interface type. OCU type interfaces are configured as "looped", and DSU type interfaces are configured as "normal". The default interface is "DSU".

When configuring CDP or CVM operation, this command configures DCE types as "normal" clocking and DTE types as "looped" clocking. The default type is DCE. For T1 lines, DS0A on T1 unassigned signalling is configurable. When a connection is not present, voice channels are converted to data channels.

cnfdclk

Configures the clocking for a data channel. In general, the clock configuration may be normal, split, or looped for an SDP or HDM (fewer options for an LDP or LDM). The clock configuration of each channel of a connection determines how the clock will be propagated through the network, and how external equipment should be synchronized.

If clocking is not set correctly, there may be no synchronization, and the connection will operate in a plesiochronous mode. Each data port can be configured independently to act as either DCE or DTE by adjusting the jumper (SDI card) or changing the adapter cable (LDI card) on the data interface card. The effect of the clocking type designated depends on whether each data port is configured as DTE or DCE. The following data clocking configurations are possible with the cnfdclk command:


DCE-Configured IPX/IGX Data Port: Normal Clocking

When the data port is configured as DCE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IPX or IGX, acting as DCE, provides both the transmit and receive data clocks to the user equipment.

Figure 8-1 :

s5254.gif


DCE-Configured IPX/IGX Data Port: Split Clocking

When the data port is configured as DCE, selecting a clocking type of "s" (for split) results in clocking as illustrated below. In "split" clocking, TT may be generated independently of RxC. The maximum data rate for split clocking is 112 kbps.

Figure 8-2 :

s5255.gif


DCE-Configured IPX/IGX Data Port: Looped Clocking

When the data port is configured as DCE, selecting a clocking type of "l" (for looped) results in clocking as illustrated below. The "Terminal Timing" signal, called TT or XTC, is simply RxC looped back from the user equipment. In this configuration, it is important that the two clocks (RxC and TT) be frequency locked. This clocking configuration is supported for all data rates.

Figure 8-3 :

s5256.gif


DTE-Configured IPX/IGX Data Port: Normal Clocking

When the data port is configured as DTE, selecting a clocking type of "n" (for normal) results in clocking as illustrated below. The IPX, acting as DTE, receives both the transmit and receive data clocks from the user equipment. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.

Figure 8-4 :

s5257.gif


DTE-Configured IPX/IGX Data Port: Split Clocking

When the data port is configured as DTE, selecting a clocking type of "s" (for split) results in the clocking as illustrated below. When the user equipment is not referenced to the network clock, the maximum data rate for this configuration is 112 kbps. The two clocks must be frequency-locked for proper operation.

Figure 8-5 :

s5258.gif


DTE Configured IPX Data Port: Looped Clocking

If you specify clocking type of "l" (looped) when the data port is in DTE mode, the result is the clocking arrangement shown in Figure 8-6. The RxC clock signal is the TT(XTC) signal looped back to the IPX or IGX by the user equipment. The network supports this clocking configuration for all data rates. The restrictions to the data clocking schemes are:

cnfict

Sets the interface control template signals. The signals that can be set using cnfict depend on the type of back card used and whether the hardware is configured for DCE or DTE. On an IPX, the applicable front cards are the SDP, LDP, FRP, CDP (for data), and FTC (for data). On an IGX, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data). Each data channel has a default interface control template for its active, conditioned, and looped near and far states. The cnfict command is used to change a control template. Each interface control lead in each template is individually configured.

When Y-cable redundancy is in effect, the control template configuration for the data channels terminating at the primary slot is also applied to the data channels of the secondary slot. Any configuration information for the secondary slot is ignored. The list below shows the configurable leads. The leads are configurable for each type of data interface supported by the IPX or IGX. The entries under the "IPX/IGX Name" column indicate the abbreviations to use when specifying input or output leads on the command line. The leads listed below show the equivalence between RS-232C, RS-232D, RS-449,V.35, and X.21 interfaces. The IPX treats leads impartially for non-interleaved connections. Any signal received on an EIA pin at one end may be transmitted to any pin at the other end, up to the maximum of 12 EIA leads on any interface type. For interleaved EIA connections, refer to the "Fast EIA" column. The column shows which leads are carried in the interleaved bytes in the data packets. All remaining leads are carried in traditional control lead packets.

Table 8-13 : cnfict -- Parameters

Parameter Description
port Specifies the data channel or frame relay port whose interface control template is to be configured. Entered as <slot.port>. On an IPX, the applicable cards are the SDP, LDP, FRP, CDP, and FTC. On an IGX, the applicable cards are the LDM, HDM, FRM, CVM, and FTM.
template Specifies which interface control template to configure for the channel and has the format <a/c/l/n/f>. Valid entries are listed below: The only valid template for a frame relay port, X.21 or V.35, is the ACTIVE template. Also, all the output leads have steady state values and do not follow local or remote inputs
Entry Template Description
a Active The "active" control template is in effect while the data channel is active (normal operation) i.e. when the connection is routed and not failed.
c Conditioned The "conditioned" control template is in effect when conditioning is applied to the data channel. The conditioned template is used when the network detects that it cannot maintain the connection because of card failures or lack of bandwidth (The connection is failed.)
l Looped The "looped" template is in effect when the data channel is being looped back in either direction. The looped template is used when addloclp or addrmtlp has been used to loop the connection within the network.
n Near loopback The "near" template is in effect when running a tstport n or an addextlp n on a port. The port is configured such that the external near modem is placed in a loopback.
f Far loopback The "far" template is in effect when running a tstport f or an addextlp f on a port. The port is configured such that the external far-end modem is placed in a loopback.
output Specifies the output lead to configure. Refer to the Configurable Lead information in the command description for valid abbreviations. Configurable output leads vary depending on the type of data interface: RS-232, V.35, X.21, or RS-449.
source Specifies how the lead is to be configured and has the format <on | off |local|remote> <input> [delay]. Valid source choices follow:
Source Options
on The output lead is asserted.
off The output lead is inhibited.
l (for local) indicates that the output follows a local lead.
r (for remote) indicates that the output follows a remote lead.
input The name of the local or remote input lead that the output lead follows.
delay The time in milliseconds that separates the "off" to "on" lead transitions. Delay is valid only when the output lead is CTS and the input lead is local RTS. "On" to "Off" lead transitions are not subject to this delay.


cpyict

Copies all control template information associated with a given channel: the active template information, the conditioned template information, and the looped template information for near and far ends. Once copied, the control template information may be edited with the cnfict command. See the cnfict command for more information on interface control templates.

On an IPX, the applicable front cards are the SDP, LDP, FRP, CDP (for data), and FTC (for data). On an IGX, the applicable front cards are the LDM, HDM, FRM, CVM (for data), and FTM (for data).

designating channel Specifies the data channel or frame relay port that will receive the copied control template information.


delcon

Removes connections from the network. After entry of the channel or range of channels to delete, a prompt requests confirmation of the selection. Connections can be deleted from the node at either end of the connection. Do not delete a connection when the node at the other end of the connection is unreachable. The unreachable node does not recognize the deletion. It is especially important not to delete a connection to an unreachable node and then connect that channel to another node.
