Location
The Location parameter specifies whether your ISX 5312/5314 is located at the central
or remote site in the network. The proper setting is essential to T7 operation. When set
to Central, the unit accepts commands from the NMI only. When set to Remote, the unit
accepts commands from the T-1 line side. T7 commands are passed out the remote
unit’s NMI port unless a modem is attached.
