Concepts
Office direction
If there are direct voice path between local office and
another office, the opposite office is the office direction
of local office.
Sub-route
If there are direct voice path between two offices,
there is a sub-route between these two offices.
Route
The association of sub-route from local office to
another office

SS7 Trunk Group
SS7 trunks can be classified as TUP ISUP
Important parameters for SS7 trunk CIC (Circuit Identification Code)
Uniquely identifies the trunk circuit between two
signaling points.
Master/slave Preventing the two offices occupying the same trunk
circuit at the same time. The office with larger signaling code usually controls the
even CIC, while the other usually controls the odd CIC.

Start circuit number, End circuit number
Unified logical numbers assigned in a particular
FCCU/FCSU module to E1 trunk circuits
The absolute value of the difference between the start
circuit number and the start circuit termination
identifier must be a multiple of 32, such as 0, 32, 64,
and 96.
Start circuit termination ID
The identifier of the start circuit timeslot of a specified
batch of trunk circuits in the resident trunk media
gateway
In UMG8900, use ”LST TDMIU” to check this value.
