c. In the Total Digits in Dialed Number cell, write the total number of
digits (0−14) expected in the dialed number; 0 is a wildcard, that is,
match any number. (Contact the service provider for the appropriate
number.)
d. After the match has been made, do
one
of the following to enable
the system to determine where to direct the call:
■ To delete digits, write the number of digits to delete (0−14).
(The system deletes from the first digit forward.)
■ To add digits, write the exact digits to enter (up to four digits)
as a prefix, for example, 7128. The factory setting is blank.
(The system adds the digits to the beginning of the number.)
5. In the Network Selection Table of the outgoing tables on Form 3b (page 7),
the dial pattern represents the dial code for specifying a long-distance
common carrier; the asterisks represent the digits in the common carrier
identification. If the telephone company has directed you to change this
information, obtain the correct entry from them. But note that the dial
pattern must come first. Entry 1 represents current national standards for
specifying long-distance carriers (asterisks represent the common carrier
code wildcard so that anything will match). Entry 0 represents the coming
national standards. The remaining entries are reserved for future use.
NOTE:
The Network Selection Table and the Special Services Table contain
factory settings that reflect U.S. standards for public telephone
network access. These factory settings can be modified to conform
to other standards. However, you should not change them unless the
telephone company explicitly instructs you to do so.
6. In the Special Services Table:
a. In the Pattern to Match cell, write the exact dial pattern to match.
(No wildcards are permitted.)
b. In the Operator cell, indicate Local Operator (OP), Presubscribed
Operator (P), or No Operator service (none) associated with the
pattern.
c. In the Type of No. cell, indicate whether the pattern is for calling
National (N) or International (I).
d. To delete digits, write the number of digits to delete (0−4). (The
system deletes from the first digit forward.)
7. For all call-by-call B-channel groups, to route all outgoing calls over a
call-by-call B-channel group, you must program the Call-by-Call Service
Table to direct the system to properly route calls. Record table entries
(maximum: 10) on Form 3b (page 8):
a. In the Pattern to Match cell, write the dial pattern to match (up to 8
digits). No wildcards are permitted.
