I need help finding out the setting on the OPTION11 to set and/or check the timing setting on a T1 link to an Avaya switch. I'm new to Nortel and telephone switches in general but have Cisco LAN/WAN experience.
The Avaya is reporting CSS (Controlled Slip Secs) errors on the link and I need to know how to verify the timing and how to set/change to correct the errors. At the moment the link is going down at lease 4 times a day.
Any help is appreciated. TIA.
