ID may be entered with the usual wild card entries
(except $).
The default ID for all source endpoints all accept numbers is 0. Thisresults
in all calls being routed based on the dialed number.
A

N

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.

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 accepta 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 longdistance calls on the local exchange if all ofthe IXCtrunks areun-
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.
