Table 3-2 Bcc15-Bc Backcard For Bcc-32, Connectors - Cisco BPX-BXM-155-8DX Installation And Configuration Manual

19.2 Gbps Operation with the BCC-4V
For the BCC-4V, the backcard is the BCC-3-BC. (These backcards are also known as the BCC
backcards).
The BCC-4V provides important features such as support for up to 19.2 Mbps peak operation with BXM
cards. Both BCCs in a node should be of the same type.
The backcard provides these interfaces:
An 802.3 AIU (Ethernet) interface for connecting the node to a CWM NMS.
•
A serial RS-232 Control Port for connecting to a VT100-compatible terminal or modem.
•
• A serial RS-232 Auxiliary Port for connecting to an external printer.
External clock inputs at T1 or E1 rates, output at 8 kHz.
•
The face plate connectors are described in Table 3-2 and Table 3-3 and shown in Figure 3-4. The
BCC15-BC is shown on the left and the BCC-3-BCC is shown on the right.
For specifications on cabling, refer to Chapter 32, BPX Switch Cabling Summary .

BCC15-BC Backcard for BCC-32, Connectors
Function
A DB25 connector for a VT100 or equivalent terminal for a basic terminal
connection enabling you to use the command line interface commands. You can
also connect to a dial-in modem for remote service support or other network
management dial-up access. This is a bidirectional RS232 communications port.
It is not used for CWM Network Management; the LAN connector is used for
CWM Network Management.
A DB25 connector for a system printer. This is a one-way, RS232 outgoing port.
DB15 connector that supplies an 8-kHz timing signal (RS422 type output that is
synchronized to the BPX switch system clock.)
A 75-ohm BNC connection for clock input. An E1 source with 75 ohm impedance
typically uses this connector. If the shield on the cable needs grounding, slide the
BCC back card out and jumped connector JP1 across its two pins.
DB15 connector for a primary and optional redundant external source of system
clock. A T1 source with 100 ohm impedance or an E1 source with 100/120 ohm
impedance typically use this connector.
A DB15 Ethernet LAN connection for connecting to a CWM NMS. You can also
connect a terminal (or NMS other than CWM) to the BPX switch LAN port via
Ethernet. However, only the CWM NMS provides full management
configuration and statistics capabilities via SNMP and TFTP.
