E&M Configuration for One T1
If no more than 12 pairs of modems are required, a
single T1 circuit can accommodate both cellular and
PSTN access. For example, time slots 1 through 12 can be
assigned to odd-numbered ports on the E&M cards (and
cellular modems in odd-numbered slots in the carrier), and
time slots 13 through 24 can be assigned to
even-numbered ports (and PSTN modems in
even-numbered slots).
