Installing Single Line Adapters (SLA)
When installed in a DEM-16 port, each SLA unit can support one DID [DDI] trunk, two single
line endpoints, or one off-premises extension (OPX).
Wall-Mounting an SLA
The SLA can be placed horizontally on a table, or it can be wall-mounted using the two L-
shaped brackets that accompany the unit.
To wall-mount an SLA unit:
1. Remove the two screws on one side of the unit
and use them to attach the two L-shaped wall-
mounting brackets. See the figure at right.
2. Position the SLA on the MDF backboard and mark
the location of the mounting screw holes on the
wall. Set the SLA aside.
3. Drive a screw into the center of each mounting
hole marking, allowing the heads of the screws to
protrude slightly. Use screws of sufficient strength
to support the SLA.
4. Hang the SLA on the screws. If necessary, adjust
the screws to ensure the SLA is held firmly in
place.
Setting Hybrid Balance Straps for a DID [DDI] Trunk on an SLA
SLAs are shipped with both ports set for single line device operation.
To change the port type if connecting a DID (DDI) trunk:
1. Remove the cover and set the corresponding port for DID (DDI) operation.
2. If necessary, adjust the hybrid balance setting from short (<.6 mi, or 1km) to long (>.6 mi,
or 1km).
3. Replace the cover.
