E&M Trunks (U.S. Only)
E. E&M TRUNKS (U.S. ONLY)
NOTE: This feature is available only on T1 or T1/E1 card circuits.
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:
• 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.
10.46 E&M trunks on the system can be programmed to support DID (see page 5-70. Other
options include DNIS and ANI (see page 5-72).
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 page 6-210 in PROGRAMMING).
10.50 The following programming is required to use the E&M feature:
1. Make sure the Advanced CO Interfaces premium feature is licensed (see page 6-97 in
PROGRAMMING).
2. Install and configure a T1 Card (T1C) or T1/E1 card, as described on page 6-126 in
PROGRAMMING. Configure the appropriate circuits as “E&M” and assign extension
numbers to the trunks.
3. Program the T1 or T1/E1 card as required. See page 6-126 (T1 Programming) in PRO-
GRAMMING.
4. Program a Call Routing Table to be used by the E&M trunk group. See page 6-319
(Call Routing Tables) in PROGRAMMING. Also see page 5-89 for more information
regarding Call Routing Tables. If it is used for DID service, set up the table using the
DID numbers.
