MERLIN LEGEND Communications System Release 7.0
Feature Reference 555-670-110
Features
Primary Rate Interface (PRI) and T1
NOTE:
In Release 6.0 and later systems (Hybrid/PBX mode only), where the
Switch Type setting is LEGEND-Ntwk or LEGEND-PBX, outgoing calls on
tandem PRI trunks are not routed using the features outlined in this section.
Instead, Remote Access and/or ARS can be used for such routing, as well
as UDP routing (see
extensions on networked switches. This cannot be changed unless the
Switch Type setting is modified.
Outgoing calls can be made by accessing a personal line, a Pool, or ARS. When a
call is placed, the system determines whether the line accessed is a PRI facility. If
so, the system performs digit analysis with the entries in the Network Selection
Table (see
Network Selection table lists the prefixes for dial access to alternative long-
distance carriers (for example, 10xxx). The Special Services Selection Table (see
Table 34) lists prefixes that represent special services, such as operator service or
international dialing (0 or 00).
In addition, if the B-channel group for an outgoing call is programmed for call-by-
call service selection, the system performs digit analysis , with the entries in the
Call-by-Call Services Table (see
indicate the service and tell the system how to delete digits and successfully route
an outgoing call.
A sample of each of these tables follows. Refer to System Programming for
information about programming these tables.
Network Selection Table. The Network Selection table lists the prefixes for dial
access to alternative long-distance carriers (for example, 10xxx). If multiple
entries in the Network Selection Table match the dialed number, the one with the
most non-wild card digits prevails. If the first digits of a dialed number (on PRI)
match any entry in this table, the entry pattern is deleted from the dialed number
and the number represented by the asterisks is used as the network selected.
Characteristics and valid entries for the Network Selection table are as follows:
There can be up to four entries (0 through 3).
The pattern can be up to eight digits.
An asterisk (*) is a wild card.
The pattern cannot begin with an asterisk but must contain at least one.
All asterisks must be at the end of the pattern and contiguous.
