UPGRADES AND ADDITIONS
Additions to the System
The following additions can be made to an existing system.
Voice Terminal Additions
Voice terminals are added to a system if unused port slots are available. The voice terminals
must be physically wired to the cross-connect field and the system. The Manager 1 or G3r-MT
terminal is used to administer these voice terminals.
Circuit Pack Additions
Circuit packs are added to provide additional port capacity for voice terminals and features. The
universal port slots available with a system allow the installation of port and service circuit packs
without a service interruption.
Carrier Additions
A port carrier increases the port slot capacity. The multi-carrier cabinet houses up to four port
carriers. Adding a port carrier interrupts service.
Cabinet Additions
With a single-carrier cabinet system, cabinet additions provide an increase in port slot capacity.
The port cabinets (up to three) are stacked on top of an existing control cabinet. Installing addi-
tional cabinets interrupts service.
Expansion Port Network Addition
An Expansion Port Network (EPN) addition increases the line capacity of the system. With a
multi-carrier cabinet system, the EPN cabinet provides additional port carriers. An Expansion
Control Cabinet equipped with a power unit, maintenance circuit pack, and a clock serves as the
basic EPN cabinet for a single-carrier cabinet system. Additional port cabinets, up to three, can
be stacked on the Expansion Control Cabinet. A fiber cable connects the EPN cabinet to the
PPN cabinet. With the Duplication, two fiber cables connect the EPN cabinet to the PPN cabinet.
Software Feature Additions
Software Feature additions allow customers to buy an added software package feature such as
Automatic Route Selection (ARS). A special login is required to activate these features that are
always resident on the system tape.
