Connector and Pinout Specifications

---

This appendix provides information about connectors and pinouts for configuration of the Cisco 6160 system.

C.1 xDSL Connectors

The backplane of the Cisco 6160 chassis contains eleven Champ connectors which connect to the xTU-C twisted-pair subscriber data interface. This connection can be made by either of the following:

•Through a POTS splitter for voice and data applications (Cisco 6160 with a POTS splitter configuration)

•Directly to the main distribution frame (MDF) for xDSL data only applications (Cisco 6160 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.

Figure C-1 xDSL Connector Pin Locations

C.2 Cisco 6160 Terminal Block Connectors

Use the terminal block connector to wire the Cisco 6160 to the power source on the fuse and alarm panel. The terminal block connector can also be used to ground the chassis. For more information on power connections and grounding procedures, see the appropriate installation chapter.

Figure C-2 shows the Cisco 6160 system power terminal block.

C.3 DS3/2DS3+8xT1 IMA I/O Card Wire-Wrap Pin Mapping

Figure C-3 shows a close-up of the wire-wrap pins.

Note For additional information about the wire-wrap pins, see the "DS3/2DS3+8xT1 IMA I/O Card Wire-Wrap Pins" section on page 1-46.

The BITS pins on Cisco 6160 DS3/2DS3+8xT1 IMA I/O card are slot specific. BITS_A pins are assigned to slot 11 and BITS_B pins are assigned to slot 10. Each BITS clock input is independent and terminated at 100 ohms.

C.5 Pinouts for the DS3/2DS3+8xT1 IMA I/O Card RJ-48c Receptacles

The RJ-48c receptacles are used for a T1 or T1 IMA configuration. Table C-3 shows the pin assignments for the receptacles.

Table C-3 Pin Assignments for the RJ-48c Receptacles 

Pin	Description
1	Receive ring
2	Receive tip
3	No connection
4	Transmit ring
5	Transmit tip
6	No connection
7	No connection
8	No connection

C.6 Console and Auxiliary Ports

The console and auxiliary ports, which are two identical serial EIA/TIA-232 ports, use RJ-45 receptacle connectors on the NI-2 card faceplate. Table C-4 shows the pin assignments, and Figure C-4 shows an RJ-45 receptacle connector.

Table C-4 Pin Assignments for the NI-2 Card Console and Auxiliary Receptacles

Pin Number	Signal
1	RTS
2	DTR
3	TXD
4	GND
5	GND
6	RXD
7	DSR
8	CTS

C.7 Ethernet Port

The Ethernet port, a 10BaseT interface with an RJ-45 receptacle connector, is on the NI-2 card faceplate. It is used to connect the Cisco 6160 to the management station, a Sun SPARCstation running Cisco DSL Manager (CDM) software. Table C-5 shows the pin assignments, and Figure C-5 shows an NI-2 card Ethernet connector.
