atcomsystems.ca/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems TTR's on a legend

I have a customer with a legend R7 and at random times will have to dial 2 or more times to get out. they will stat dialing and the phone will disconnect. the t-1 provider says their circuit is good. I have looked in the switch and I have no alarms other than code 0c03 ( all ttr's unavailable ). Is there a way to test each ttr.
I am still lookig thur my docs to find out what cards have what number of ttr's. :confused:

This should get you going:

https://support.avaya.com/edoc/docs/legend/leg61in1.pdf

It has a discussion on how many TTR's are required, which cards provide them and how many, and how to test them.

Thanks,That just what I was looking for.
So that means that if my customer has

in cabinet 1
Processor
408 gs/ls
008 mlx
008 mlx
008 mlx
Ds1

in cabinet 2
mlm 007
0012
then that means they only have 2 ttr's ?

Yup, only 2 TTR's, but I'm not sure they come into play on OUTBOUND calls on T1 by multiline phones.

Check the DS1 for errors, Maintaince, Slot, 05, Enter, Error Events.

You could also give an extension dial out access to the pool with the DS-1 channels, make sure each channel is labled uniquely, then place test calls to make sure each channel is working properly.

doesn't the 007 have a couple ttrs too?

in the error event is as follows:

mis 001
slp 002
es 000
bs 000
sec 000
fs 000

ttr's tested good.
