Cisco AS5200 Universal
Access Server Overview
The Cisco AS5200 universal access server is a versatile data communications platform that
provides the functions of an access server, a router, modems, and terminal adapters (TAs)
in a modular chassis.
The access server provides the greatest benefit for midsized organizations or service
providers that need to centralize processing capabilities for mobile users and
telecommuters.
The access server is optimized for high-speed modem access and is ideally suited for all
traditional dial-up applications, such as access to a host, electronic mail, file transfer, and
dial-in access to a LAN.
System Components
The access server consists of the following components:
•
One 19-inch modular chassis with three slots for feature cards and a high-speed
backplane
•
•
•
•
•
Two serial WAN ports
One Ethernet LAN port
One console port for local administrative access
One auxiliary port for remote administrative access
An integral AC or DC power supply

Feature Cards
The access server includes three slots in which you can install a combination of the
following feature cards:
•
•
•
Dual T1/Primary Rate Interface (PRI) card
Dual E1/PRI card
Carrier card
You can install one of the following feature cards in any of the three available slots:
•
•
Dual T1/PRI card with integrated channel service units (CSUs)
Dual E1/PRI card with one slot for an optional 12-port module
In the two remaining slots, you can install carrier cards.
Dual T1/PRI Card
The dual T1/PRI card routes incoming digital T1 lines to the 6-port or 12-port modules. The
dual T1/PRI card provides RJ-48C connectors to terminate trunks. The dual T1/PRI card
performs all necessary equalization and gain functions to support 6000 feet of 24-gauge
unshielded cable. This card complies with all Bell Core standards relating to T1
(ANSI T1.403) alarms, loopbacks, and error detection. The dual T1/PRI card is equipped
with integrated CSUs.
The dual T1/PRI card handles up to 48 digital signal level 0 (DS-0) channels from two
trunks. Each channel carries either a pulse code modulation (PCM)–encoded voice channel
or digital data. The dual T1/PRI card supports 64-kbps clear channel operation for data or
voice channels and feature group B operation for voice channels.

Dual E1/PRI Card
The dual E1/PRI card (see Figure 1-4) is installed in the Cisco AS5200 to provide physical
termination for two E1/PRI lines. The card is designed to support the E1 cable standard of
30 Bearer (B) channels for voice and data, one Data (D) channel for signaling, and one
channel for framing. Each channel transmits at up to 64 kbps for a combined total of 2.048
Mbps for each E1/PRI line.
The Cisco AS5200 is used to service calls from users accessing remote services using a
variety of network protocols. Calls are terminated in the Cisco AS5200 through up to 60
modems or modem/terminal adapter combinations. Your access server can support a
combination of MICA modems, Microcom modems, and V.110 terminal adapters. User
data can then be routed through the Ethernet or synchronous serial ports on the
Cisco AS5200 chassis.

You can install up to two carrier cards in any unpopulated slot of the access server chassis.
Each carrier card includes two slots in which you can install any combination of the
following 12-port modules:
•
•
•
V.34 12-port module
56K 12-port module
V.110 12-port module

56K 12-port module
V.110 12-port module
In an access server with a dual T1/PRI card installed, you can install up to four 12-port
modules for a total of 48 ports. If your access server includes a dual E1/PRI card, you can
install up to five 12-port modules for a total of 60 ports. The dual E1/PRI card (see
Figure 1-4) includes an extra slot for a 12-port module, which provides you with 12 extra
ports to terminate up to 60 lines.
Note The 12-port modules are not included unless specified by your order. You can order
bundled systems that include 12-port modules or you can order the modules separately.
Refer to the section “Getting Help” in the appendix “Troubleshooting the Universal Access
Server” for ordering information.
V.34 12-Port Module
Each modem on the V.34 12-port module supports V.42bis data compression and uses the
Hayes Smartmodem AT and V.25bis command sets. The Microcom Networking Protocol
(MNP) and V.42 error-correction protocol standards provide error-free performance. The
modem offers MNP Class 10 with Adverse Channel Enhancements (ACE). MNP 10
includes:
•
•
•
•
Multiple connection attempts during autoreliable link negotiation
Negotiated speed upshifts
Aggressive adaptive packet assembly
Dynamic Transmit Level Adjustment
The V.34 module supports the following protocol and modulation standards:
•

56K 12-Port Module
The 56K 12-port module uses Rockwell’s K56Flex technology. The module can send data
at up to 56 kbps and receive data at up to 33.6 kbps. Connections at 56 kbps start as analog,
are converted to digital, and are not converted back to analog at the service provider.
Because one conversion (from digital to analog) is omitted, speeds of up to 56 kbps are
possible. However, the actual speed that you can achieve with the module depends on the
condition of your local telephone network.
Note The initial release of the 56K module operates at up to 33.6 kbps (V.34) and offers
a firmware upgrade to enable 56 kbps (K56Flex) when it is available.
The 56K 12-port module supports the following protocol and modulation standards:
•
K56Flex modulation at 56000, 54000, 52000, 50000, 48000, 46000, 44000, 42000,

for:
•
Adapting the slower asynchronous data rates of older equipment to the faster data rate
of ISDN B channels
•
Cellular data applications over the Global System for Mobile Telecommunications
(GSM)
•
Asynchronous connectivity for European ISDN TAs
The V.110 12-port module includes the following features:
•
•
•
•
•
Compatible with the ITU-T V.110 recommendation
•
Supports up to 60 GSM calls
Optimized for GSM cellular data networks
Compatible with major GSM switches
Compatible with legacy ISDN V.110 terminal adapters
