ID may be entered with the usual wild card entries
(except $).
The default ID for all source endpoints all accept numbers is 0. This results
in all calls being routed based on the dialed number.
A
CCEPT
N
UMBER
Designates which numbers this endpoint passes on toward the Network
(PSTN). The accept list may consist of multiple entries. The numbers are
defined using the following “wild cards”:
Example:
1-800-$ only permits toll free long distance calls to 1-800. If this were used,
then a second accept number would need to be specified (NXX-XXXX) per-
mitting local numbers to be dialed.

Write security: 3 Read security: 5
Instructs ATLAS 550 in which order to search for an accept number match.
Normally, all searches are set to primary. The secondary search selection
forces ATLAS 550 to only accept a call at this endpoint if all primary end-
points are unavailable.

All long distance calls should go out a PRI directly to an IXC (MCI, ATT,
etc.), and local calls should go out a T1 to the LEC. It may be desirable to
place long distance calls on the local exchange if all of the IXC trunks are un-
available (busy or in alarm). In this case, the primary accept number for the
local exchange would be N$, and the secondary accept would be 1$.
X = Any digit 0 through 9
[1,3,5]=Any of these digits
0 = Default value
X = Any single digit
N = Any single digit 2 through 9
$ = Any number of digits of any value
9 =Thisspecificnumber
[1,2,3...] = A single digit in this group
Any specific entry takes precedence over a wild card. For
example, if endpoint A was designated as $ while endpoint B
accepted 963-800X, then an incoming call to 963-800X would
only be accepted by endpoint B.
