Introduction

Cisco has supported the Cisco IGX 8400 series platforms since Cisco IOS Release 12.1(5)YA. The

Cisco IGX 8400 series platforms can now function as components of Cisco end-to-end voice

architecture. The Cisco IOS software runs only on the URM; all other components of the Cisco IGX

8400 series platforms run Switch Software (SWSW). The minimum SWSW release to support URM is

9.3.20.

The URM is a Cisco IOS software-based IP router blade that enables users to provision Voice over IP

(VoIP), Voice over ATM (VoATM), Multiprotocol Label Switching (MPLS), and IP services on a Cisco

IGX 8400 series platform. The voice and routing capabilities of the URM have been derived from the

Cisco 3660 series routers, and the ATM capabilities of the URM have been derived from the existing

enhanced universal switching module (UXM-E) that is used on the Cisco IGX 8400 series platform.

Additionally, Cisco IOS command-line interface (CLI) commands are now available on the

Cisco IGX 8400 series platforms, which allows configuration of IP services.

The URM interoperates with all Cisco IOS software-based voice products and supports 30 voice

channels with high-complexity codec types and 60 voice channels with medium-complexity codec types.

Note Only digital voice ports are supported on the URM; analog ports are not supported.
