This chapter provides an overview of the Cisco AS5400XM universal gateway, 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 AS5400XM universal gateway is 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 AS5400XM universal gateway provides enhanced performance for processor-intensive voice and fax applications. The Cisco AS5400XM universal gateway provides you with a cost-effective platform for deploying the widest range of IP-based services.

Chassis Components

The Cisco AS5400XM universal gateway chassis has a motherboard, a high-speed backplane, and seven slots for dial feature cards (DFCs) or voice feature cards (VFCs).

The backplane accepts DFC carrier cards which allow online insertion and removal (OIR) of the DFCs and VFCs.

The chassis consists of the following components:

One building integrated timing system (BITS) interface port

One alarm port

Two Gigabit Ethernet (2GE) 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

Product Serial Number Location

The serial number label for the Cisco AS5400XM universal gateway is located on the rear of the chassis, on the right side. (See Figure 1-3.)

Note The serial number for the Cisco AS5400XM universal gateway is 11 characters long.

Cisco Product Identification Tool

The Cisco Product Identification (CPI) tool provides detailed illustrations and descriptions showing where to locate serial number labels on Cisco products. It includes the following features:

A search option that allows browsing for models using a tree-structured product hierarchy

A search field on the final results page making it easier to look up multiple products

End-of-sale products are clearly identified in results lists

The tool streamlines the process of locating serial number labels and identifying products. Serial number information expedites the entitlement process and is important for access to support services.

The Cisco Product Identification tool can be accessed at the following URL:

Dial Feature Cards

Each dial feature card (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.

Channel-associated signaling (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 AS5400XM universal gateway supports only one type of WAN DFC at a time. For more information, see the "Mixing WAN DFCs" section on page 4-2.

Power Supply

The power system consists 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.

Note The grounding architecture for the Cisco AS5400XM universal gateway is isolated DC return (DC-I).
