Call-By-Call Service Table - AT&T MERLIN LEGEND Release 3.0 Programming Summary Manual

Call-by-Call Service Table

Call-by-Call Service Table
When a call is placed on a Call-by-Call B-channel group, a specific service is
selected. The selected service depends on the match between the dialed
digits and the table entries. A service must be specified; otherwise the entry is
ignored.
The Call-by-Call table can contain up to 10 entries. Each entry can contain up
to 10 patterns, each with a maximum of eight digits. If a dialed number
matches two patterns, the longer pattern takes precedence. For example,
212555 matches both 212555 and 212, but the system will match the longer
pattern. In addition to patterns, the Call-by-Call table can be used to specify
from 0 through 8 digits to be deleted (the default is 0).
If the last entry in the table is empty (that is, no pattern is specified), this entry
is used as a default and matches any pattern and type of call.
If ARS (Hybrid/PBX only) is used, ARS selects the route. If the route points to a
Call-by-Call B-Channel group, Call-by-Call service selects the network
service. ARS Call-by-Call service is integrated according to the specified
bearer capability (voice, data, or both) for each feature. In addition, ARS digit
deletion/addition may help specify the service selected by the Call-by-Call
feature. See "Automatic Route Selection" for more information.
