The Cisco AS5300 universal access server is a versatile data communications platform that provides the functions of an access server, router, and digital modems in a single modular chassis. The access server is intended for Internet service providers (ISPs), telecommunications carriers, and other service providers that offer managed Internet connections, as well as medium- to large-sized sites that provide both digital and analog access to users on an enterprise network. By terminating both analog and digital calls on the same chassis simultaneously, the access server provides you with a clear, simple, and easy migration path from today's analog dial access services to tomorrow's digital dial access services.
The access server consists of the following components:
The access server includes three slots (see Figure 1-2) in which you can install a combination of feature cards.
In any one slot you can install your choice of:
In the remaining two slots you can install your choice of:
You can install a quad T1/PRI card (Figure 1-3) in any unpopulated slot of the access server chassis.
The quad T1/PRI card includes four RJ-45 ports. Cables are not included with the card; however, port pinouts are listed in the appendix "Cabling Specifications for the Universal Access Server."
A 10-position rotary switch allows the user to chose which of the four ports is selected for monitoring through the bantam jacks (TXMON, TXIN, TXOUT and RXMON, RXIN, RXOUT). The LED labeled MON at each port illuminates to indicate that port has been selected for monitoring. Only one port can be selected at a time. None of the ports is selected when the switch is set to the OFF position.
You can install a quad E1/PRI card (Figure 1-4) in any slot of the access server chassis.
The quad E1/PRI WAN card includes four RJ-45 ports for terminating 120-ohm balanced lines or 75-ohm unbalanced lines. Cables are not included with the card. However, cable specifications and port pinouts are listed in the appendix "Cabling Specifications for the Universal Access Server."
A 10-position rotary switch allows the user to chose the number of ports that are terminated as 75-ohm unbalanced lines. If the LED labeled 120 at each port is on, it indicates the input impedance of that port is set to 120 ohms. If it is off, the impedance is set to 75 ohms.
Jumper settings on the card can be used to configure the 75-ohm unbalanced ports so the receive shield is connected to ground. Impedance selection switch settings and receive shield jumper positions are described in the next chapter, "Preparing to Install the Universal Access Server."
You can install up to two MICA carrier cards (Figure 1-5) in any unpopulated slot of the access server chassis. Each MICA carrier card includes 10 slots in which you can install 6-port modem modules. Each 6-port module includes 6 modems. Therefore, in a fully populated MICA carrier card, you can have up to 60 modems. Or, in a fully populated access server chassis, you can have up to 120 modems.
You must install the 6-port modem modules in the MICA carrier card. The 6-port modules cannot be used as standalone cards and they cannot be installed in Microcom carrier cards.
Cisco's MICA DSP technology assures network managers of the highest performing, highest flexibility, standards-compliant access platform. These DSPs are incorporated into the MICA 6-Port modem module. As outlined in the MICA carrier card section, ten of these modem modules can be configured on each of two carrier cards for a total of 60 ports per card, or a total of 120 ports per chassis.
You can install up to two Microcom carrier cards (Figure 1-7) in any two slots of the access server chassis. Each Microcom carrier card includes two slots in which you can install any combination of 12-port modem modules, as described below.
The modules connect through the Microcom carrier card and the system backplane to a quad T1/PRI or quad E1/PRI card installed in the access server chassis. Data is transmitted or received on T1 or E1 lines connected to the quad T1/PRI or quad E1/PRI card and then routed to the 12-port modules installed in the Microcom carrier card.
The access server supports any combination of the following 12-port modules:
You must install the 12-port modules in the Microcom carrier card. The 12-port modules cannot be used as standalone cards and they cannot be installed in MICA carrier cards.
Either an AC or DC power supply is available. The power supply provides DC power to the installed feature cards via connectors on the backplane.
The internal power supply is a four-output switching power supply with power factor correction and regulated outputs.
The specifications of the access server are listed below.
