Primary
 External Paging uses an output on the GCD-CP10 of the Primary System.
 A PGD(2)-U10 ADP must be used if External Paging is required in the Secondary
Systems.

Bandwidth

The following example shows the approximate bandwidth used for the NetLink
signaling:
Bandwidth signaling for 1 call = 4kb

Bandwidth of 1 voice call (G.711, VIF=20ms) = 90kbps

If there are 100 calls (average talk time of five minutes) between the linked
communication servers for one hour:
Signaling data total is 4kb x 1000 calls divided by 3600 seconds = 1.11kbps

Voice data total is 1000 calls divided by 60/5 x 90Kbps = 7.5Mbps

Using the above calculation, the signaling data is smaller than the voice data. So,
in determining the bandwidth needed, using the voice bandwidth number for both
the voice and data allows adequate bandwidth.
Conference Block
The number of conference blocks in NetLink is the same as with a stand-alone

communication server.
Voice Mail
The InMail must be installed in the Primary System.

Only one Voice Mail or InMail can be installed in NetLink network.

Voice Mail can be installed in the Primary or Secondary System.
