This chapter provides an overview of the Cisco AS5400 and Cisco AS5400HPX universal gateways, a versatile voice and data communications platform that provides high performance, high density, and hot swappability in only two rack units. (See Figure 1-1 and Figure 1-2.)

The Cisco AS5400 and Cisco AS5400HPX are intended for large companies and service providers who require dense and scalable solutions to create new multi-service access networks, replace existing hardware, or expand and enhance their current access offering. The Cisco AS5400HPX provides enhanced performance for processor-intensive voice and fax applications. The Cisco AS5400 and Cisco AS5400HPX provide you with a cost-effective platform for deploying the widest range of IP based services.

Note Unless specifically noted, all references to the Cisco AS5400 also apply to the Cisco AS5400HPX.

Chassis Components

The Cisco AS5400 universal gateway chassis has a system board, high-speed backplane, and seven slots for dial feature cards (DFCs). The chassis includes four backplane slots. Three backplane slots accept DFC carrier cards and the other backplane slot accepts one DFC. Each DFC carrier card accepts two DFCs which allow online insertion and removal (OIR).

Tips To help identify your universal gateway, starting with Cisco IOS Release 12.2(11)T, the show version and show diag commands will identify the universal gateway as an AS5400 or AS5400HPX. Prior to this release, these commands showed the universal gateway as an AS5400, even if it was an AS5400HPX.

The chassis consists of the following components:

One Building Integrated Timing System (BITS) interface port

One alarm port

Two Fast Ethernet (2FE) LAN ports

Two T serial ports for backhaul WAN support

One fast console port for local administrative access

An integral redundant AC or DC power supply, with two power input lines

Dial Feature Cards (DFCs)

Each DFC is a 5.1 by 13 inch PCI-based interface board. The following is a brief description of the trunk types supported:

North American robbed-bit signaling (RBS) is supported on T1 trunks, including a variety of North American RBS protocol, framing, and encoding types on these trunks.

CAS is supported for E1 trunks, with R2 signaling.

Many countries require an E1 R2 variant. Per-country defaults are provided for supervisory and inter-register signaling.

The CT3 DFC provides physical line termination for a channelized T3 ingress trunk line, and it uses an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.

Universal access (analog modem or digital calls) is supported when an interface is configured for ISDN PRI signaling. PRI signaling is available for both T1 and E1 trunks.

In any single DFC slot, you can install your choice of:

One T1 dial feature card

One E1 dial feature card

One T3 dial feature card

Note The Cisco AS5400 supports only one type of WAN DFC at a time. For more information, see the "Mixing WAN DFCs" section.

Power Supply

The power system is comprised of a fully redundant switching power supply with two AC (or DC) inputs to the main power modules. Each input and output is 100 percent fully redundant, with dual fans for added reliability.

The output of each power module is rated at 300 watts (nonredundant mode), and is composed of four independent output voltages: 3.3V, 5V, 12V and -12V. AC input units have power factor correction, and low harmonic distortion. Units that are in redundant mode run at one-half the power capability. If a power supply failure occurs, these units are capable of powering the complete system either at the input side or the DC load side. Power failures are reported through environmental monitoring software.
