[Asterisk-Users] Meridian Option 11 with T100P

	I append configuration of asterisk and meridian for DTI and DTI/PRI.
The problem is that I don't know how to change default law for T100P card,
actually it is running in u-law, but some of my nortel equipments are
working in a-law . I know that it is possible to change meridian law but I
am unable to do it because there are existing services (PRI, DTI ) that are
working in a-law.

I have configured T100P to work with meridian in two modalities and both
work ok, expect by the sound quality problems. In the two cases meridian DTI
Card (NTAK09) is used

T100P as Digital Trunk Interface (DTI) no D-Channel and T100P as DTI/PRI.

REQ
NOTE: The 1.5 Mb DTI/PRI needs a daughter board for controlling D-CHANNEL.
This daughter board is not required when working only as DTI. Also is
recommended to use a daughter clock controller card to avoid error related
to clocking in my case I did not use this clock controller card. Nortel
Release is 18 with Networking facilities

VERSION 1411
RELEASE 18
ISSUE 30 + H

The purpose of interconencting *PBX to meridian is to offer conferencing
facilities, record conversation and to work as a bridge between Hard
IP-Phones and meridian phones


So, I would like to know how to change T100P card from u-law to a-law

Please help!

Can you also post the Nortel config? What release software are you 
running on the Option 11?
