E. E&M TRUNKS (U.S. ONLY)
NOTE:
10.43 E&M trunks are special trunks that tie two distant telephone systems together. They
allow the users of either telephone system access to the users and resources of the other tele-
phone system.
10.44 E&M trunks, like standard trunks, may be programmed to ring in to call routing tables,
individual stations, multiple stations, or hunt groups, or as a DISA call. (If programmed to ring
in at a single station, the E&M call follows any programmed forward.)
10.45 When a call is placed over an E&M interface, one of the following things happens:
•
•
•
•
10.46 E&M trunks on the system can be programmed to support DID (see
options include DNIS and ANI (see
10.47 E&M trunks are programmed into trunk groups. The trunk group programming deter-
mines day and night mode outgoing access for the trunks.
10.48 When the system is in the default configuration, all E&M trunks are configured for
DTMF signaling. If necessary, some or all of the trunks can be reprogrammed for dial-pulse
signaling through DB Programming.
10.49 The DID/E&M [DDI in Europe] Receive Busy Instead Of Camp-On station flag deter-
mines whether E&M and DID callers receive busy signal or receive ringback and camp on
when calling a busy station. In the default state, busy tones are disabled and the callers hear
ringback while camped on to the called station. This flag is programmed on a station-by-station
basis (see
10.50 The following programming is required to use the E&M feature:

MANUAL VERSION 11.0 – May 2008
This feature is available only on T1 or T1/E1 card circuits.
If programmed for "Immediate" start type, the calling system immediately begins send-
ing the dialed digits to the receiving system.
If programmed for "Wink" start type, the systems perform a "handshake" to allow the
receiving system to signal that it is ready to receive the digits dialed by the other sys-
tem. (This is the default start type.)
If programmed for "Delay Dial" start type, the calling system waits until its E&M Dial
Delay timer expires before sending any digits to the receiving system.
If programmed for "Dial Tone" start type, the calling system waits until it receives dial
tone from the other system before sending any digits.

Make sure the Advanced CO Interfaces premium feature is licensed (see
PROGRAMMING).
Install and configure a T1 Card (T1C) or T1/E1 card, as described on
PROGRAMMING. Configure the appropriate circuits as "E&M" and assign extension
numbers to the trunks.
Program the T1 or T1/E1 card as required. See
GRAMMING.
Program a Call Routing Table to be used by the E&M trunk group. See
(Call Routing Tables) in PROGRAMMING. Also see
regarding Call Routing Tables. If it is used for DID service, set up the table using the
DID numbers.
