Chapter 2 Solution Components
Media Gateways
Platform Components
The Cisco AS5400 and AS5400HPX media gateways support two 10/100 Mbps Ethernet LAN ports and
have seven slots for Dial Feature Cards (DFCs). One or two DFC slots can be used for trunk feature
cards, and the remaining slots can be used for Digital Signal Processor (DSP) cards. All cards are hot
swappable.
Both media gateways support the 8-port E1/PRI termination trunk feature card and the 60- and
108-Universal Port Feature cards. The 8-port E1/PRI card provides physical termination for E1, PRI, or
intermachine trunks (IMTs). The universal port feature cards support the modem, wireless, voice, and
fax calls. Modem-management features are available for troubleshooting, including modem status,
real-time call-in-progress statistics, modem activity log, hard/soft busy out, and modem firmware
upgrade.
The maximum configuration is 16 E1 lines (two E1/PRI DFCs) and five 108-Universal Port DSPs in the
seven slots. This configuration provides a total of 496 calls (determined by 31 calls on each E1 line). An
alternative option would be to use four 108-Universal Port Feature cards and one 60-Universal Port
Feature card to better match the maximum number of calls, but this is a balance between requirements
for redundancy (DSP cards are pooled), inventory management issues due to a mix of cards, and cost of
the cards. See Table 2-7 and Table 2-8 for sample AS5400 and AS5400HPX bundles.
The AS5400 and AS5400HPX share the same architecture and the same adaptors, and run the same
Cisco IOS code. The AS5400HPX has a slightly higher performance on E1 lines due to differences in
the motherboard and better memory management, and is thus able to sustain more calls.
The AS5400 and AS5400HPX require the MGCP + NAS Package that is part of Cisco IOS IP PLUS.
Refer to the most current Release Notes for Cisco Multiservice Packet Network Solution for details of
the required Cisco IOS release.
Cisco Access Registrar
The Cisco Access Registrar (CAR) is an optional component that can provide the authentication,
authorization, and accounting (AAA) features required for the dial services authentication. CAR is a
standards-based Remote Authentication Dial-In User Service (RADIUS) server.
