Connector and Pinout Specifications

This appendix provides information about connectors and pinouts for a Digital Off-Hook (DOH) configuration of the Cisco 6100 with NI-1 system.

Cisco 6100 Chassis Connectors

This section describes the Cisco 6100 chassis connectors and pinouts for the following:

• Connectors to the Cisco 6110

• System Management Bus

• Cisco 6100 Terminal Block Connector

• Alarm Contacts

Connectors to the Cisco 6110

Cisco Systems provides three Cisco 6110 chassis cables for the connection of the CAP ATU-C modem pools in the Cisco 6100. Figure C-1 shows the Cisco 6110 chassis cable connector.

System Management Bus

To route the system management bus between the Cisco 6100 and the Cisco 6110, use the 26-pin SCSI cable. Refer to the "Connect the Cisco 6110 Controller" section for more information.

Figure C-2 shows the 26-pin SCSI cable connector.

Table C-1 lists the system management bus connector pinouts.

Cisco 6100 Terminal Block Connector

Use the terminal block connector to wire the Cisco 6100 to the power source on the fuse and alarm panel. For more information on power connections, see the "Attach Cisco 6100 and Cisco 6110 Power Connections" section.

The terminal block connectors will accept 12 to 18 American Wire Gauge (AWG) copper solid or stranded wire. Figure C-3 shows the Cisco 6100 Series power terminal block.

Alarm Contacts

The Cisco 6100 with NI-1 system provides the following CO alarm interface contacts:

• E2A---You use E2A contacts to connect to a standardized management interface for intraoffice alarm transport.

• Visual---Typically, you use visual alarm contacts to connect to CO visual alarm systems.

• Audible---Typically, you use audible alarm contacts to connect to CO audible alarm systems.

These alarm contacts are located on the Cisco 6100 backplane (P14, P15, P17), as shown in Figure C-4.

Each connector pinout (P14, P15, P17) includes a dedicated side-by-side pair of wire-wrap alarm contacts for three alarm types:

• Minor (MIN)---Normally open.

• Major (MAJ)---Normally open.

• Critical (CRIT)---Normally closed to allow critical alarm activation in the event of a loss of power to the system. If power is lost, the critical alarm contacts open, causing a CO alarm to be activated.

An automatic cutoff (ACO) input is also located adjacent to the audible alarm contacts. When closed, the ACO input deactivates audible alarm contacts. The system controller module faceplate contains a button labeled ACO that you can press to disable the CO audible alarms on site. All alarm contacts are rated at 2A maximum current and 220 VDC maximum voltage.

Table C-2 lists the alarm contact pinouts shown in Figure C-4.

Cisco 6110 Chassis Connectors

This section describes the Cisco 6110 chassis connectors and pinouts for the following:

• Champ Connectors

• Cisco 6110 System Management Bus Connector

• Cisco 6110 Terminal Block Connector

Champ Connectors

The backplane of the Cisco 6110 chassis contains four Champ connectors, which are used to transfer data between the Cisco 6110 and the Cisco 6120. Pin locations are the same for all Champ connectors on the Cisco 6110.

Figure C-5 shows connector pin locations for the Cisco 6110 connectors. Pin locations are the same for all Cisco 6110 connectors.

Note You must screw all cables into the backplane and tie wrap Champ connectors (see "Cabling Guidelines" section).

Cisco 6110 System Management Bus Connector

The Cisco 6110 system management bus connector carries management information between the Cisco 6110 and the Cisco 6100 chassis.

Figure C-6 shows the pin locations for the Cisco 6110 system management bus connector, a 26-pin SCSI cable connector.

Table C-3 lists the connector pinouts for each system management bus connector.

Cisco 6110 Terminal Block Connector

Use the terminal block connector to wire the Cisco 6110 to the power source on the fuse and alarm panel. For more information on power connections, see the "Attach Cisco 6100 and Cisco 6110 Power Connections" section.

The terminal block connectors will accept 12 to 18 American Wire Gauge (AWG) copper solid or stranded wire. Figure C-7 shows the Cisco 6110 chassis power terminal block.

Cisco 6120 Chassis Connectors

The backplane of the Cisco 6120 provides three sets of connectors:

Pin locations are the same for all Champ connectors on the Cisco 6120 (see Figure C-8).
