Pin Assignments

This appendix describes the electrical connections of ports on the Cisco 6200 advanced digital subscriber line access multiplexer (DSLAM).

This appendix provides the following pin assignments:

• UTP connectors: 10 female Champ connectors for subscriber traffic. The Champ connectors on the rear of the chassis present the same interface as the Champ connectors on the dangler cables (J1 to J10). (The dangler cables attach to the backplane UTP connectors shown in Figure A-1.)

• Alarm relay connector: a 34-pin male connector (J39) for alarm relay signals.

• Auxiliary port: a 9-pin female D-type connector (J40) for an auxiliary port.

• Console port: an RJ-45 connector marked CNSL on the management processor card (MPC).

• Ethernet management port: an RJ-45 connector marked ENET on the MPC.

Refer to Figure A-1 for the locations of the connectors on the rear of the chassis.

Items Not Used in This Release

The following fixtures are not used in this release. Except where otherwise indicated, these items are located on the rear panel of the DSLAM.

• A 10-pin jumper (J36) for setting the shelf ID (located on the inside of the backplane)

• Two connectors (J014 and J034) for redundancy switching

• A 50-pin male Champ connector (J41) for a T1 line

• A 10-pin jumper (J42) for clocking

• A 9-pin female D-type connector (J44) for a serial port to a secondary MPC

• A 34-pin male connector (J45) for alarm relay signals from a secondary MPC

• Two BNC connectors (J47 and J48) for a DS3 line

• Two BNC connectors on the front of the chassis. One is under the fan tray; the other is in a recessed area to the left of the power entry modules (PEMs). (These connectors are present on only a few systems.)

• Two BNC connectors (ETH1/J65 and ETH2/J66) for 10Base2 (Thinnet/RG-58) Ethernet

Caution Do not remove the terminators from the BNC connectors. Doing so prevents the cards within the chassis from communicating with each other.

A.1 UTP Connectors for Subscriber Traffic

Ten 50-pin Champ connectors on the backplane provide unshielded twisted pair (UTP) connections that carry ADSL signals (subscriber traffic) between the Cisco 6200 DSLAM and the POTS splitter. Attached to each connector is a dangler cable. One end of the dangler cable mates with the Cisco 6200 backplane; the other end terminates with a female 50-pin Champ connector.

Each Champ connector on the backplane, and thus each dangler cable, serves one subscriber line card (SLC) slot in the Cisco 6200 chassis. The ten dangler cables, J1 through J10, serve slots 5 through 14 respectively. The pinout for the connectors is provided in Table A-1.

A.2 Alarm Relay Connector

Table A-2 lists the pin assignments for backplane connector J39, the alarm relay connector. The alarm relays provide relay contact closures. 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 the change in status. For general information on the alarm relay feature, see "Alarm Relay Connection" in "Hardware Description."

The alarm relay connector provides an alarm cut-off circuit that you can wire to your external alarm device. Connect the alarm device so that it can close the contact between pins 13 (ACO C) and 30 (ACO O) on the Cisco 6200 alarm relay.

The alarm relay connector also provides 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.

A.3 Auxiliary Port

J40 is a 9-pin male connector on the backplane for an EIA/TIA-232 serial port connecting to the management processor card (MPC). J40 is an auxiliary port that can be used to connect devices such as terminals, modems, or laptop computers to the Cisco 6200. Table A-3 shows the pin assignments.

A.4 Console Port

The console port, a serial EIA/TIA-232, uses an RJ-45 connector on the MPC faceplate. Table A-4 shows the pin assignments.

A.5 Ethernet Management Port

The Ethernet port, a 10BaseT interface with an RJ-45 connector, is on the MPC faceplate. It is used to connect the Cisco 6200 to the management station, a PC running Cisco 6200 Manager software. Table A-5 shows the pin assignments.
