This port is a serial RS232 DCE port configured for 8 bits,

no parity, and 1 stop bit.

2.8.3 User Port

The USER port (labeled ‘USER – IN/OUT’) is located on

the rear panel. The function of this port is identical to that of

the PTT port with the following exception. The USER port

does not allow the clearing of PTT data and the PTT port

does not allow clearing the USER data. This is explained

further in Section 4.4 on page 4-5. The physical connection

is a 6-pin modular connector with the following pinout

assignments.

2.8.4 Chassis Network Management

The operation of the EM8000 in the 12-slot chassis is simi-

lar to the stand-alone operation. Within the chassis, each

element is physically connected to the next element in a

daisy chain fashion. Signals from all modules are gathered

and presented on consolidated 6-pin modular connectors on

the rear panel, labeled ‘NMS IN’ and ‘NMS OUT’. The

front panel ‘SUPV’ port operates in the same fashion as in

the stand-alone unit.

When used in the chassis, the communications bus is auto-

matically tied into each unit, allowing single point interfac-

ing to the chassis. Cards may be inserted and removed from
