Digital provisioning is provided by the loop-start protocol and Dual-Tone Multi-Frequency (DTMF)
signaling. ShoreTel Voice Switches support the following:
 ESF or D4 framing formats
 B8ZS or AMI line coding.
Analog Wink-Start Trunks (Analog DID)
Analog wink-start trunks allow external callers to dial a user’s phone number directly, without having to
use an auto-attendant or operator. Analog wink-start trunks support only inbound calls; they are not
capable of handling outbound calls.
Analog wink-start trunks support the following:
 Inbound calls (outbound calls are not supported)
 ANI
 DID
 DNIS
Analog provisioning is provided by the wink-start protocol and Dual-Tone Multi-Frequency (DTMF)
signaling.
If ANI is being used, the star (*) key must be used to delimit the ANI digits from the DID/DNIS digits —
that is:
 <DID>
 <DNIS>
 *<ANI>*<DID/DNIS>*

use an auto attendant or operator. Digital wink-start trunks support both inbound and outbound calls.
Digital wink-start trunks support the following:
 Inbound calls
 Outbound calls
 ANI
 DID
 DNIS
Digital provisioning is provided by the wink-start protocol, which is often called E&M wink-start, and
Dual-Tone Multi-Frequency (DTMF) signaling.
