(minimum=1, maximum=10) and assigns numbers as you want. For example, you may want only
the last four digits of similar numbers in order to differentiate between them. DNIS is typically
only available on inbound 800 service.
Outbound lines may or may not have a phone number assigned. If a phone number is assigned by
the Service Provider, these lines can be used to receive incoming calls.
The T1 Interface Card receives DID or ANI information using MF (Multi-Frequency) or DTMF
(Dual Tone Multi-Frequency) tones. The T1 Interface Card automatically determines if MF or
DTMF is present on a call-by-call basis. Dial pulses are not generated or used by the T1 Interface
Card.
When ordering T1 service, request a framing mode of ESF (Extended Super Frame), but be aware
that many Service Providers supply only D4 framing. ESF provides troubleshooting capabilities that
are not available with D4. If ESF framing mode is available, request B8ZS (Bit Eight Zero
Suppression) line coding. If ESF is not available, AMI (Alternative Mark Inversion) line coding is
usually used.
