BPX 8600 Series Wide Area Switch
Cisco Site Preparation Guide
3-50
The BCC-4 is fully compatible with legacy function modules (BNI, ASI), which use one 800 Mbps
input and one 800 Mbps output link. The new BXM modules and the BCC-4 cards feature the dual
receiver serial interface unit (DRSIU) ASIC that takes advantage of the two 800 Mbps in output
direction.
• BCC-3-32, BCC-3-64
The BCC-3-32, BCC-3-64 control cards include a 16 x 16 switch fabric that provides 9.6 Gbps
of peak throughput.
• The ASM card has the following features:
— Front card and associated back card (ASM-BC)
— One card required per node
— Support functions—Telco-compatible alarm indicators, controls, relay outputs, node power
monitoring, monitoring of shelf cooling fans and temperature, sensing for presence of other
cards installed in the BPX 8600 shelf.
Broadband Switch Group
The broadband witch module cards (BXM), designed with Stratm technology, provide standard
interfaces for connecting to cell-based customer premises equipment (CPE) through ATM
User-Network Interface (UNI) or to non-Cisco networks through a Network-to-Network (NNI)
interface. Stratm technology provides the industry's first ATM Forum-compliant (TM V.4.0)
available bit rate (ABR) virtual source/virtual destination (VS/VD) capability in custom ASICs.
There are three high-density BXM card types:
• BXM-T3/E3
The BXM-T3/E3 is a T3/E3 ATM interface card for the BPX 8600 switch. This interface card
provides either 8- or 12-T3/E3 ATM ports per card, with a card configuration option for trunk or UNI
applications. The BXM-T3/E3 supports 16,000 or 32,000 connections per card. The supporting back
card options provide up to 12 ports and can be used with the 8-port BXM or the 12-port BXM.
• BXM-155
The BXM-155 is an OC-3c/STM-1 ATM high-capacity interface card for the BPX 8600 series
switch. Operating at the standard SONET/SDH rate of 155.520 Mbps, this interface card
provides either 4- or 8-OC-3c /STM-1 ATM ports per card, which can be configured for trunk or
UNI applications. The BXM-155 supports 16,000 connections per card. Multimode,
single-mode, and single-mode long reach optical interfaces are available.
• BXM 622
The BXM-622 is an OC-12c/STM-4 ATM high-capacity interface card for the BPX 8600 series
switch. Operating at the standard SONET/SDH rate of 622,08 Mbps, this interface card provides
either 1- or 2-OC-12c/STM-4 ATM ports per card, which can be configured for trunk or UNI
application with full bi-directional 622-Mbps (OC-12/STM-4) throughput per slot in the BPX
8600 switch. The BXM-622 supports 16,000 or 32,000 connections per card. Single-mode,
single-mode long reach, and 1550 nm extra long reach optical interfaces are available.
