DSX-1 and E1 IMA/IMA+ LIM Overview
Xedge Inverse Multiplexing (IMA) LIMs for ATM can be used with a variety
of controllers listed in
physical DS1 or E1 interface. The Xedge PCX and PCL controllers must use
the DSX-1/E1 "IMA+" LIMs. Front panel, jumpers, connectors and pinouts
are the same for all IMA-capable LIMs, except where noted.
Front Panel Indicators
• IS (In Service) GREEN LED ON indicates all the enabled links are in the
up state, or no link is enabled. LED OFF indicates an operational problem;
LIM may require a restart. LED blinking indicates at least one link is in a
diagnostics state.
• AL (Alarm) RED LED ON indicates a fault on at least one enabled link.
LED OFF indicates none of the enabled links has a fault condition.
• IS and AL blinking indicates lost communication between LIM and
controller.
Front Panel Connectors
• LINK 0-7 is 50-pin Telco for transmit/receive tip and ring signals.
LINK 8-15 is 50-pin Telco for transmit/receive tip and ring signals.
• IMPORTANT! Refer to
(Figure 5-25) to comply with all domestic and international standards.
Front Panel Jumper
The X9 jumper is used primarily by the factory to set the LIM for Boot
Mode in order to load software. For normal operation, the jumper should
be in the Normal position (Pins 2 and 3) to store the jumper. Only set
jumper to Boot Mode under the guidance of GDC service representative.
