Other considerations for PRI-to-T1 conversion
On a MAX unit with multiple lines configured for ISDN (PRI), each outgoing call from the
PBX uses the first channel available on any PRI line. To specify a PRI line for outgoing calls,
the PBX must preface its dialed numbers with the dialing prefix specified by the Ch N
TrnkGrp parameter in the Line N profile for the line used by the PBX. Also, you must enable
trunk groups by setting the Sys Config profile’s Use Trunk Grps parameter to Yes.

For incoming calls, note that the MAX unit does not forward the called number to the PBX.
Example of PRI-to-T1 configuration
Following is an example of a configuration for PRI-to-T1 conversion. Only the relevant
parameters are shown. In this example, line 2 is connected to the PBX, and line 1 is configured
for normal ISDN signaling. (The complete line 1 configuration is not shown.)

Assigning bandwidth to a nailed link
A nailed link is always active. Both ends of the link must assign the same number of channels
to the link. However, channel assignments do not have to match. For example, a nailed link
that uses a single channel might have channel 1 nailed at the local end and channel 12 nailed at
the remote end.
to the link. However, channel assignments do not have to match. For example, a nailed link
that uses a single channel might have channel 1 nailed at the local end and channel 12 nailed at
the remote end.
To designate channels for a nailed line, open Net/T1 > Line Config > Line Config profile and
make sure that the line whose channels you are designating is set to Trunk (that is, 1st Line or
2nd Line must be set to Trunk). Then open the subprofile (Line 1 or Line 2) for that line, and
configure the nailed channels. For each channel that is to be nailed, set the Ch N parameter to
