System A: Receives
outside dial-plan routed
PRI data call at 64 kbps.
System A: PRI dial-plan routing deletes
555, checks local dial plan, then finds
number in non-local dial plan. Routes via
non-local UDP Pattern 3 to PRI tandem
trunk pool 3366 at 64 kbps, Data only
<
System B: First part of 2B data call
arrives at video system, Ext. 7002. When
the second call is received, the data speed
is 128 kbps.
●
System A: Receives
outside dial-plan routed
PRI-ANI voice call.
System A: PRI dial-plan routing deletes
555, checks local dial plan, then finds
number in non-local dial plan. Routes via
non-local dial plan Pattern 2 to PRI
tandem trunk pool 3364, Voice and Data

System B: Arrives at Ext. 6871,

System A: Receives
outside DID call.
System A: DID receives 6871, checks
local dial plan, then finds number in non-
local dial plan. Routes via UDP Pattern 2
to PRI tandem trunk pool 3364, Voice and
Data <
System B: Voice call arrives at Ext. 6871,
displays as outside call on tandem trunk:
●
System A: Receives
outside dial-plan routed
PRI voice call and is not
available. Integrated
VMI calling group
provides coverage.
System A: PRI dial-plan routing deletes
555, checks local dial plan. Call is sent to
integrated VMI calling group 771 (with
VMI conversion number 7999). The
system finds the group member in the
non-local dial plan. Routes via UDP
Pattern 05 to PRI tandem trunk pool 3360.
UDP routing absorbs 7999 and prepends
771 (System A’s centralized integrated
VMI calling group extension).
<
System B: Calls ring into centralized
VMS/AA and calling information indicates
an outside call. When the caller leaves a
message, the Message Waiting light
update is sent over the private network to
extension 3105 on System A.
