Pin Assignments

This appendix describes the electrical connections of ports on the Cisco 6160 digital subscriber line (DSL) access concentrator.

This appendix provides the following pin assignments:

• Subscriber connectors: 11 female RJ-21 Champs for UTP connections, located on the back of the chassis.

• Wire wrap connector: a 30-pin male connector for alarm relay and building-integrated timing source (BITS) clock signals, located on the I/O card at the back of the chassis.

• Circuit breaker alarm relay terminals: two terminal blocks located on the back of the chassis.

• Console and auxiliary ports: two RJ-45 connectors on the NI-2 card.

• Ethernet management port: an RJ-45 connector on the NI-2 card.

Refer to Figure A-1, Figure A-2, and Figure A-3 for the locations of the connectors on the chassis.

Subscriber Connectors

Eleven 50-pin Champ connectors on the back of the chassis provide unshielded twisted pair (UTP) connections that carry asymmetric digital subscriber line (ADSL) signals (subscriber traffic). The subscriber connectors are numbered JC1 through JC11. They connect either to the POTS splitter (for voice-and-data lines) or directly to the subscriber (for data-only lines). The pinout for these connectors is provided in Table A-1. Figure A-4 shows a subscriber connector.

Wire Wrap Connector

This section provides a table of pin assignments for the wire wrap connector on the I/O card. The wire wrap connector, which is located on the I/O card on the back of the Cisco 6160 chassis, provides relays for critical, major, and minor alarms and building-integrated timing source (BITS) clock connections. This connector supports both wire wrap and socket type connections; the six-pin connector that mates with each of the five headers is Molex 26-03-3061.

Note The relay for the circuit-breaker trip alarm is wired through the small green terminal blocks on the rear of the chassis---not through the wire wrap connector.

---

Both the alarm relays and the BITS clock connections are optional. If you connect the alarm relays, they transmit critical, major, and minor alarms to a separate, external alarm device. The alarm device uses a bell, light, or some other signal to alert people to changes in status. If you connect the BITS interface, the Cisco 6160 can receive a clock signal from a T1 line.

One of the alarm relay functions provided by the wire wrap connector is an alarm cut-off circuit that you can wire to your external alarm device. To use this feature, connect the alarm device so that it can close the contact between pin 5 and pin 6 in row P4.

There is one set of contacts for audible alarms and one set for visual alarms. In Table A-2, audible alarms signals begin with AUD and visible alarm signals begin with VIS. You can use either or both sets of contacts.

Figure A-5 shows a wire wrap connector.

Circuit Breaker Alarm Relay Terminals

The circuit breaker alarm relay feature is wired through two terminal blocks on the rear of the chassis. The terminal blocks are labeled BRKR 1 and BRKR 2 and they are located directly behind the PEMs. BRKR 1 serves the bottom PEM and BRKR 2 serves the top PEM (if there is one).

Console and Auxiliary Ports

The console and auxiliary ports, which are two identical serial EIA/TIA-232 ports, use RJ-45 connectors on the NI-2 faceplate. (The console and auxiliary ports are the same on all versions of the NI-2.) Table A-3 shows the pin assignments, and Figure A-6 shows an RJ-45 connector.

Table A-3: Pin Assignments for the NI-2 Console and Auxiliary Connectors

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

Ethernet Port

The Ethernet port, a 10BaseT interface with an RJ-45 connector, is on the NI-2 faceplate. It is used to connect the Cisco 6160 to the management station, a Sun SPARCstation running Cisco DSL Manager (CDM) software. (The Ethernet port is the same on all versions of the NI-2.) Table A-4 shows the pin assignments, and Figure A-7 shows an NI-2 Ethernet connector.
