Chapter 2 Cisco IGX 8400 Series Cards
Universal Router Module
• Local and remote loopbacks for port and circuit testing
• A single RJ-45 console port for direct Cisco IOS CLI access for serviceability (also used for initial
configuration of the router module)
• Cisco IOS voice features available in Cisco IOS Release 12.1(5)YA, including switched voice,
VoI P, an d VoATM
• DSP549 voice processing capability
• ADPCM voice compression at 32 kbps or 24 kbps per G.726
• LDCELP voice compression at 16 kbps per G.728, on a maximum 30 channels per card
• CSACELP compression at 8 kbps on 30 channels per G.729 or 60 channels per G.729A
• A-law or mu-law voice encoding on a per-channel basis; for voice connections that use PCM,
ADPCM, or G.729A, the URM can operate in either 24-channel mode (T1) or 30-channel mode (E1)
URI-2FE2V Back Cards
The BC-URI-2FE2VT1 and BC-URI-2FE2VE1 back cards provide T1 or E1 digital voice interfaces for
the URM. BC-URI-2FE2V features include:
• 2 T1 or 2 E1 ports capable of digital voice support
• 2 10/100 Ethernet ports with ISL support
• Onboard MC68LC302 processor with 128 KB of local SRAM
• 2 Rockwell/Brooktree Bt8370 T1/E1 framers with integrated LIUs
• 3 LEDs per port including Carrier Detect, Alarm, and Loopback
• Onboard RJ-45 connectors with transition cable breakout to physical layer
• On-card TDM drop-and-insert capability, any time slot to any time slot between ports
• Onboard processor for signaling, FDL, and line management
• T1 CSU and DSU line build outs
• T1 D4SF and ESF framing
• ANSI T1.403 Annex B/V.54 loopup/down code recognition, network loopback, and user-initiated
loopbacks
• BERT capability (2^6 and 2^32 patterns not supported)
• Full support for Blocker TR54016 and ANSI T1.403 loopbacks for CT1 and FT1
• E1 structured (ITU G.704) and unstructured (ITU G.703) operation
• AMI, B8ZS, and HDB3 line coding
See Figure 2-43 to locate LEDs and interfaces on the URM back card. See Table 2-56 for a description
of the physical ports on the back card, Table 2-57 for a description of the LEDs on the URI back card,
and Table 2-58 for a description of the LEDs located on the installed VWIC.
Different URIs are made by inserting the appropriate VWIC into the basic BC-URI-2FE2V back card.
Two VWICs can be used: the VWIC-2MFT-T1 for T1 connections and the VWIC-2MFT-E1 for E1
connections.
