Connector and Pinout Specifications

This appendix provides information about connectors and pinouts for a Direct Connect 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:

xDSL Connectors

The backplane of the chassis contains six 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 (Direct Connect with a POTS splitter configuration)
Directly for data only applications (Direct Connect 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

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

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 one of the following sections:

The terminal block connectors will accept 12 to 18 American Wire Gauge (AWG) copper solid or stranded wire. Figure C-2 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-3.

Figure C-3: Alarm Contacts

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-1 lists the alarm contact pinouts shown in Figure C-3.

Cisco 6120 Chassis Connectors

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

Four Champ connectors for connection to subscriber pairs
Four Champ connectors for connections to the PSTN for voice service
Four Champ connectors for connection of xDSL signals to the Cisco 6110

Pin locations are the same for all Champ connectors on the Cisco 6120 (see Figure C-4).
