Cisco Systems 8600 Series manual Backcard Line Module for BCC-32, Connectors, Connector Function

Broadband Controller Card (BCC-32, BCC-3, BCC-4)

backcards). The BCC-3 and the BCC-32 are functionally interchangeable, while the BCC-4 provides additional features such as support for 19.2 Mbps operation by the BXM cards. Both BCCs in a node should be of the same type. The backcard provides the following interfaces:

•

•

•

•

An 802.3 AIU (Ethernet) interface for connecting the node to a StrataView Plus 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 3-2and Table 3-3and shown in Figure 3-5.For information on cabling, refer to Appendix B, BPX Switch Cabling Summary.

Table 3-2	Backcard (Line Module) for BCC-32, Connectors
BCC-C	BCC-C
Connector	Function
CONTROL	A DB25 connector for a VT100 or equivalent terminal for a
	basic terminal connection using command line interface
	commands. Can also be connected to a dial-in modem for
	remote service support or other network management dial-up
	access. This is a bidirectional RS232 communications port.
	This is not used for SV+ Network Management; the LAN
	connector is used for SV+ Network Management.
AUXILIARY	A DB25 connector for a system printer. This is a one-way,
	RS232 outgoing port.
XFER TMG	DB15 connector that supplies an 8-kHz timing signal (RS422
	type output that is synchronized to the BPX switch system
	clock.) This signal can be used to synchronize a co-located
	IPX.
EXT TMG	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.
EXT TMG	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.
LAN	A DB15 Ethernet LAN connection for connecting to a
	StrataView Plus NMS. A terminal or NMS other than SV+ can
	also be connected to the BPX switch LAN port via Ethernet.
	However, only the SV+ NMS provides full management
	configuration and statistics capabilities via SNMP and TFTP.
