That's correct. The T1 spans on the DS3 are completely independent of the clocking on the DS3. The D-channel and timing is something that will be handled by your upstream Telco and the switch that you'll be connecting to. Or, your own box.. ;) > What I would really like to do is have one D channel coming in on the T3 > and have it split between each of the T1/PRI or even better one D > channel per quad (I know Asterisk can do that). > > Is it possible?

They are solid, reliable and work well. Adtran's technical support is amazing. When you purchase an MX-2800, you are immediately given access to the Adtran Carrier support group, which doesn't even blink about sending out an advance replacement unit overnight if you ask. -- Vice President of N2Net, a New Age Consulting Service, Inc.
