MG-PRI/PRA
Open
ATRK
command and specify trunk data on Virtual Speech Channel. For more information, refer to
the Command Manual. The following is an example for assigning channel data of T1 and E1 respectively.
Note that the data setting for Dch must be performed after the
ACIC1
command assignment.
Note:
Be sure to assign route data by ARTD/ARTI in advance before assigning trunk data by ATRK.
Note:
Do not assign any trunk data to Group 0 of Unit 0 in even number Module group because it cannot be used
with
MG-PRI/PRA .
Note:
The total number of B-channels must not exceed 460 per two Module Group (MG) pair.
i.e. MG2/3, MG4/5 and MG6/7.
STEP 8
Specify Destination Point Code
Open ADPC command and register Point Code on Virtual Speech Channel and Virtual Signaling Channel.
Note that the Point Code must be different from the Point Code for CCIS. (ISDN does not actually use the
Point Code but it is necessary to develop the Office Data.)
Note:
NDM command (ADPCN) cannot be used here.
STEP 9
Specify CSC Information
Open ACSC command and assign Virtual Speech Channel into the even numbers (130
∼
254) of the CSC
group, and Virtual Signaling Channel into the odd numbers of the CSC group.
Note:
NDM command (ACSCN) cannot be used here.
T1(23B+D) setting
:Virtual Signaling Channel
:Virtual Speech Channel
Note : Virtual trunk occupies 1HW (4-Group). For example, if one channel is registered for Virtual Trunk,
the whole HW is occupied exclusively for the Virtual Trunk.
