MXE III
Dual T1 Card
Version 13.0.0.80



I spent all day today with tech support trying to get the T1 card on the 3300 to sync up to the T1 card on the Cisco.

our 3300 replaced a Siemens system that they were able to dial through a T1 to the router and have it go to an unknown system in Canada. Im trying to use my T1 to do the same but it never Greens up.

Programming from the router shows the following:

controller T1 0/0/0
clock source internal
cablelength long 0db
ds0-group 1 timeslots 1-24 type e&m-wink-start
!
controller T1 0/0/1
cablelength long 0db


so i set my netsync source to the T1 Card PLID. i also set my circuit descriptor for E&M

DTSTAT READ always shows this though

Universal T1 5 1 2 1
Link is not available, sync not present
duty bit
cycle framing error
Time (%) losses slips rate
------------------------------------------------
16:00 0 0 0 0
------------------------------------------------



I tested my cable with a cable tested and programmed the 2nd port in the T1 card and looped them with the cable and was able to get the ports to sync up so I feel the cable and the card are good.

Any ideas on how i can get this T1 card to talk to the Cisco Router? The card on the router is a VWIC2-2MFT-T1/E1




Below are notes from Tech Support in case i missed anything in my descrption:

Removed Release Link Trunk programming, removed Vendor Interworking Type form the Link Descriptor.
Reviewed all programming, has channels programmed, and placed in a trunk group.
Verified cable pinouts.
Reviewed Cisco running config, it indicates it will get WAN timing and propagate to the T1 circuit, and indicates circuit uses QSIG signalling.
Tech has tested cable with his cable tester.

No synch with Cisco, no duty cycle.

Deprogrammed and reprogrammed T1 circuit, and assigned net synch.
Still no synch or duty cycle.
Cleared dt stats, no change.

Over licenced system with a second Digital Link, programmed up second circuit and programmed one channel with a link descriptor that flipped over the TX/RX paris.
Circuit worked perfectly.

Tech connected back to Cisco.
We tried manipulating the link descriptor multiple ways, but no luck.
Tried maxing out the cable length in DSX mode in an attempt to increase signal sensitivity, still no synch.
 
and indicates circuit uses QSIG signalling."

is your link programmed as Qsig ?

With Qsig only 1 side can be the master , try changing that

do you get flashing green LED when using a loopback RJ45 ?



If I never did anything I'd never done before , I'd never do anything.....

and due to an endless stream of MiCollab , MiCC issues
Life would be simpler If only they tested products properly before releasing them .....
