If the DMS100 switch can talk signalling directly with Asterisk, without
an STP, it should be possible to use a single timeslot for ss7
signalling, so with 2 T1 you could have 47 voice calls and one
signalling channel. This is common with E1 setups. Also with E1 its
common for a timeslot to be statically switched over to an STP (semi
permanent call), allowing for access to the signaling network without a
dedicated physically separate signaling link, but that's not usual in T1
land.
But what you ask is technically possible... However its important to
PROPERLY LEARN SS7 terms to be able to communicate with your supplier.
SS7 is a CARRIER LEVEL PROTOCOL. However people insist on winging it
without proper training.
Its like trying to become a backbone internet provider without properly
learning inter and intra network routing protocols (like BGP and OSPF).
If you knew the general SS7/ISUP knowledge, you could quickly find the
information you're looking for on Google.
PS: I live in E1 land... I'm just quoting information from the top of my
head. I have no need for T1+SS7. E1+SS7 is a little simpler with
Asterisk than T1+SS7 due to 56kbps data links, ANSI ISUP/SS7 and some
other quirks.
Good luck. You'll need it.

If I were to get a 2 span T1 card for Asterisk... and connect it to a
Nortel DMS100... can I run call traffic over the T1 and run SS7
signaling FOR the T1 over the other port?
Is there documentation on doing this anywhere?
