HCM6 provides 12 voice channels at high complexity and 24 channels at medium complexity. You can

install one or two HCMs in a Cisco MC3810, but an HCM can not be combined with a VCM in the same

chassis.

Cisco AS5300 Universal Access Server

The Cisco AS5300 Universal Access Server includes three expansion slots. One slot is for either an Octal

T1/E1/PRI feature card (eight ports) or a Quad T1/E1/PRI feature card (four ports), and the other two

can be used for voice/fax or modem feature cards. Because a single voice/fax feature card (VFC) can

support up to 48 (T1) or 60 (E1) voice calls, the Cisco AS5300/Voice Gateway system can support a total

of 96 or 120 simultaneous voice calls. The use of VFCs requires Cisco IOS release 12.0.2XH or later.

Cisco AS5300 VFCs are coprocessor cards, each with a powerful reduced instruction set computing

(RISC) engine and dedicated, high-performance DSPs to ensure predictable, real-time voice processing.

The design couples this coprocessor with direct access to the Cisco AS5300 routing engine for

streamlined packet forwarding.

Cisco AS5800 Universal Access Server

The Cisco AS5800 Universal Access Server consists of two primary system components: the Cisco 5814

dial shelf (DS), which holds channelized trunk cards and connects to the PSTN, and the Cisco 7206

router shelf (RS), which holds port adapters and connects to the IP backbone.

The dial shelf acts as the access concentrator by accepting and consolidating all types of remote traffic,

including voice, dial-in analog and digital ISDN data, and industry-standard WAN and remote

connection types. The dial shelf also contains controller cards voice feature cards, modem feature cards,

trunk cards, and dial shelf interconnect cards.

One or two dial shelf controllers (DSCs) provide clock and power control to the dial shelf cards. Each

DSC contains a block of logic that is referred to as the common logic and system clocks. This block of

logic can use a variety of sources to generate the system timing, including an E1 or T1/T3 input signal

from the BNC connector on the DSC's front panel. The configuration commands for the master clock

specify the various clock sources and a priority for each source (see the “Clock Sources on Digital T1/E1

Voice Ports” section on page 66).

The Cisco AS5800 voice feature card is a multi-DSP coprocessing board and software package that adds

VoIP capabilities to the Cisco AS5800 platform. The Cisco AS5800 voice feature card, when used with

other cards such as LAN/WAN and modem cards, provides a gateway for up to 192 packetized voice/fax

calls and 360 data calls per card. A Cisco AS5800 can support up to 1,344 voice calls in split-dial-shelf

configuration with two 7206VXR router shelves.
