combinations of superloop connections to the Fiber Remote Multi-IPE
Interface. The flexibility of superloop use allows for system optimization,
which depends on the specific system configuration and traffic
requirements.
Maintenance functions
The Fiber Remote Multi-IPE Interface provides a DB-9 female (MAINT)
connector at the rear of the unit on the I/O panel. This connector is used
as the MMI terminal port at both the local and the remote sites.
This MMI terminal is used to perform the following functions:
•
•
•
•
•
•
The SDI connector, also located on the Fiber Remote Multi-IPE Interface
I/O panel, is used to connect the Fiber Remote Multi-IPE Interface to an
SDI card in the local system. An MMI terminal at the local site or at a
Remote IPE site can access the system through this SDI port at the local
site and perform configuration, maintenance, and test functions of the
system.
A modem port (MODEM) is also provided on the I/O panel. This DB-9
female connector connects a modem to the Fiber Remote Multi-IPE
Interface. The modem is used to connect an MMI terminal, which may
be located at a maintenance center. This maintenance center may be
located in a different city, but by using a modem and public or private
telephone facilities, it is able to access the Fiber Remote Multi-IPE
Interface equipment at the local and the remote sites. It can also access
the local SDI port for local system maintenance. This access is allowed
only to the system TTY and the MMI terminals directly connected to the
Fiber Remote Multi-IPE Interface MAINT port.
A Fiber Remote Multi-IPE Interface in a multiple unit configuration can
be accessed by logging in on an MMI terminal. An MMI terminal can
then access the local system for system maintenance or access a Fiber
Remote Multi-IPE Interface at the local or remote sites for maintenance
