Installation and connections
The QPC250 RLT circuit pack can be inserted into any trunk-pack position
on a peripheral equipment (PE) shelf. The circuit-pack handling precautions
must be observed when installing trunk packs in PE shelves. Installation
procedures for trunk-circuit packs are provided in
Meridian 1 system

.
When telephone lines connected to the trunk circuit are exposed to foreign
voltages by direct contact or induction—for example, by power-line crosses
or by lightning—protection devices must be installed at the customer’s
premises. These devices must be capable of providing a path to ground from
the tip and ring leads for foreign voltages that exceed a 600-V peak.
Typical cross-connections between a QPC250 RLT trunk at a Remote site
and a QPC70 CO trunk at the Main site are shown in
