Features
■ Transfer without Consultation: In Release 2.0 and later, pressing the
More button on an MLX display telephone that is a transfer destination
shows the original CdPN (before digit analysis). The same display
applies to transferred PRI calls routed by dial plan.
Outgoing Calls
Call-by-Call Service Selection is a Release 2.0 and later feature for outgoing
calls that allows a group of B-channels to carry a variety of supported PRI
services programmed in the Call-by-Call Services Table (see Table 32). The
assignment criteria are based on the outgoing routing digits and the bearer
capability (voice, data, or both) of the originating endpoint. In Releases 1.0 and
1.1, an outgoing call is carried on a static B-channel, that is, a B-channel
dedicated to one specific service.
Outgoing calls using Call-by-Call Service Selection can be made by accessing
a DFT, a Pool, or Automatic Route Selection (ARS). When a call is placed, the
system determines if the line accessed is a PRI facility. If so, the system
performs digit analysis with the entries in the Network Selection Table (see
Table 30), which lists the prefixes for dial access to alternate long distance
carriers (for example, 10xxx), and the Special Services Selection Table (see
Table 31), which allows the user to specify 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 Table 32). The entries in this table indicate
the service and the required digit deletion information to successfully route an
outgoing call.
A sample of each of these tables follows. Refer to System Programming for
information about programming these tables.

* is a wild card, representing the chosen network.
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:
