This appendix describes the electrical connections of ports on the Cisco 6260 digital subscriber line (DSL) access concentrator.
This appendix provides the following pin assignments:
Refer to Figure A-1 and Figure A-2 for the locations of the connectors on the chassis.
Ten forward-facing 50-pin Champ connectors at the top of the chassis provide unshielded twisted pair (UTP) connections that carry asymmetric digital subscriber line (ADSL) signals (subscriber traffic). 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-3 shows a subscriber connector.

This section provides a table of pin assignments for the wire wrap connector on the I/O modules (both OC-3c and DS-3 versions). The wire wrap connector, which is located near the top of the Cisco 6260 chassis, provides alarm relay and building-integrated timing source (BITS) clock connections.
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 the change in status. If you connect the BITS interface, the Cisco 6260 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 5.
The connector also provides contacts for the following features, all of which can be used (or not used) separately:
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.
You can wire the alarm relay contacts as normally open (NO) or normally closed (NC). (Except for the alarm cut-off circuit, ACO, which can be wired NO only.) Use common (CO) pins for both the NO and NC wiring methods.
| Wiring Method | Pins to Use |
|---|---|
Normally open | Pin 2 in rows 1, 2, 3, 4 (NO) |
Normally closed | Pin 3 in rows 1, 2, 3, 4 (NC) |
Figure A-4 shows a wire wrap connector.
| Row | Pin 1 | Pin 2 | Pin 3 | Pin 4 | Pin 5 | Pin 6 |

Row 1 | PEM1_BR_CO1 | PEM1_BR_NO2 | PEM1_BR_NC3 | PEM2_BR_CO | PEM2_BR_NO | PEM2_BR_NC |
Row 2 | AUD_CRIT_CO4 | AUD_CRIT_NO | AUD_CRIT_NC | AUD_MAJ_CO5 | AUD_MAJ_NO | AUD_MAJ_NC |
Row 3 | AUD_MIN_CO6 | AUD_MIN_NO | AUD_MIN_NC | VIS_CRIT_CO7 | VIS_CRIT_NO | VIS_CRIT_NC |
Row 4 | VIS_MAJ_CO | VIS_MAJ_NO | VIS_MAJ_NC | VIS_MIN_CO | VIS_MIN_NO | VIS_MIN_NC |
Row 5 | Reserved | Reserved | Reserved | Reserved | ACO_NO | GND8 |
Row 6 | RX_BITS_TIPA9 | RX_BITS_RINGA | RX_BITS_GND/GND | RX_BITS_TIPB | RX_BITS_RINGB | RX_BITS_GND/GND |
The console and auxiliary ports, which are two identical serial EIA/TIA-232 ports, use RJ-45 connectors on the NI-2 faceplate. Table A-3 shows the pin assignments, and Figure A-5 shows an RJ-45 connector.
| Pin Number | Signal |
|---|---|
1 | RTS |
2 | DTR |
3 | TXD |
4 | GND |
5 | GND |
6 | RXD |
7 | DSR |
8 | CTS |
The Ethernet port, a 10BaseT interface with an RJ-45 connector, is on the NI-2 faceplate. It is used to connect the Cisco 6260 to the management station, a Sun SPARCstation running Cisco DSL Manager (CDM) software. Table A-4 shows the pin assignments, and Figure A-6 shows an NI-2 Ethernet connector.
| Pin Number | Signal |
|---|---|
1 | TX+ |
2 | TX- |
3 | RX+ |
4 | Unused |
5 | Unused |
6 | RX- |
7 | Unused |
8 | Unused |
