8.4 Configuring Voice SLIM LIDs
Voice SLIM LIDs are hardware configured using jumper banks. In order to
reconfigure a voice SLIM LID, the relevant jumper bank(s) must be removed and
reinserted in the required location. Jumper locations are silk-screened on the
SLIM LID.
8.4.1 E&M 2/4-wire
The E&M 2/4-wire SLIM LID is hardware configurable, with a number of jumper
banks, to match:
• a 2 or 4 wire interface
• line impedance
• signalling type
• normal or reverse signalling
NOTE:
Normal signalling is also known as B side or Channel Equipment side.
