T1 A/B Robbed-bit E&M Protocol
Make sure that the switch to which the system is connected is programmed
with the following options:
• The T1 interface uses wink start robbed-bit E&M signaling on a link using
D4 framing with zero code suppression (ZCS).
• The E1/T1 interface outpulses dual tone multifrequency (DTMF) tones at
7 pulses per second when originating outbound calls and requires DTMF
when taking inbound calls.
