1 Descriptions MIX 56 User Manual

DSX Tracer Lamp: One per DSX jack; used to locate cross-connects.

ESD Jack: One per chassis. Used when performing maintenance to pre- vent harmful electrostatic discharge to electronic components.

Fanning Strip: One row per wire-wrap pin field. Used to properly dress cross-connect wires.

M13 Cards: One or two per system. Houses the active circuitry for multi- plexing functions. One card for nonredundant systems, two cards for re- dundant systems.

M13 Card Ejector Handle: One per M13 card. Used to remove and re- place cards in the chassis.

Craft Port: One per system. Female DB-9, RS-232 serial connector used to access the craft interface locally.

Wire-Wrap Pinfield: 28 DS1 pin fields per system. Used for routing and cross-connecting DS1 signals. When using as a mux, Telect recommends using these DS1 wire-wrap connections. This method of connecting the low speed signals does not provide signal patching capabilities.

NOTE

To use a system as a multiplexer with full DSX capabilities, connect incom- ing and outgoing DS1 signals to the front wire-wrap pins.

LEDS

The LED status indicators on the MIX 56 front panel are grouped into the following categories:

•DSX Tracer Lamps: When the tracer lamp (TL) pins of the cross-con- nected modules are connected, the lamp lights when a plug is inserted in the monitor port of one of the modules.

•M13 Card Status LED: One per card.

◊Lights green for the active card.

◊Lights orange for a standby card with no critical alarms.

◊Solid red on the standby card indicates the card has detected a criti- cal alarm condition or is otherwise nonoperational.

◊Flashing red indicates a card cannot resolve an alarm condition.

◊Unlit means the card is not receiving power, or has a failure in the processor circuitry.

•LED Panel Indicators: See the next subsection.
