Connector and Pinout Specifications

This appendix provides information about connectors and pinouts for configuration of the Cisco 6260 system.

C.1 xDSL Connectors

Ten female RJ-21 (Champ) subscriber connectors are located at the top of the Cisco 6260 chassis, facing forward. These 50-pin sockets provide the DSL subscriber connections. Each subscriber connector serves three line card slots. This connection can be made by either of the following methods:

Through a POTS splitter for voice and data applications (Cisco 6260 with a POTS splitter configuration)
Directly for data only applications (Cisco 6260 without a POTS splitter configuration)

Figure C-1 shows connector pin locations for the xDSL Champ connectors. Pin locations are the same for all Champ connectors.

C.2 I/O Module Connectors

This section provides information about the external interface connectors for the Cisco 6260 I/O module.

C.2.1 E3 I/O Module BNC Connectors

Three sets of two vertically paired E3 75-ohm coaxial BNC connectors reside on the left side of the I/O module faceplate. The P1 connectors serve as the network trunk connections. The P2 and P3 connectors support subtending to additional Cisco 6260 chassis. Each set has both a receive (RX) connector and a transmit (TX) connector.

Figure C-2 shows a close-up of the E3 connectors.

C.2.2 E1 I/O Module RJ-48c Connectors

Four sets of two vertically paired E1120-ohm RJ-48c connectors are located on the left side of the I/O module faceplate. Each E1 interface can be used as a WAN trunk connection, an individual E1 subtend link, a connection to an IMA subtending group, or a connection to an IMA group trunk interface.

Figure C-3 shows a close-up of the E1 connectors.

C.3 I/O Module Wire-Wrap Pins

There are 36 wire-wrap pins located on the right side of each I/O module faceplate that support

Central office alarm relay interfaces (visual and audible critical, major, and minor)
BITS clock input circuits
Wire-wrap and socket-type connections

Table C-1 lists the pinout descriptions for the I/O module wire-wrap pins and Figure C-4 shows a close-up of the I/O module wire-wrap pins.

¹PEM = power entry module
²BR = breaker
³AUD = audible
⁴CRIT = critical alarm
⁵MIN = minor alarm
⁶VIS = visible
⁷MAJ = major alarm
⁸RX_BITS = receive building-integrated timing source

C.4 Console and Auxiliary Ports

The console and auxiliary ports, which are two identical serial EIA/TIA-232 ports, use RJ-48 receptacle connectors on the NI-2 card faceplate. Table C-2 shows the pin assignments, and Figure C-5 shows an RJ-48 receptacle connector.

2	DTR
3	TXD
4	GND
5	GND
6	RXD
7	DSR
8	CTS

C.5 Ethernet Port

The Ethernet port, a 10BaseT interface with an RJ-48 receptacle connector, is on the NI-2 card faceplate. It is used to connect the Cisco 6260 to the management station, a Sun SPARCstation running Cisco DSL Manager (CDM) software. Table C-3 shows the pin assignments, and Figure C-6 shows an NI-2 card Ethernet connector.
