The person said BRI, PRI *or* TRUNK side T1s. You have trunk side
T1s. A DID is a phone number on one of your T1s, not the T1 itself.

DID actually stands for Direct Inbound Dial, not digital inbound
dialin. A DID is where a company gets a set of phone lines from
the telco (like say 24) but actually gets 90 phone NUMBERS. DID allows
the PBX to send the phone call directly to a specific extension
depending on the phone number dialed.
