OPERATION
The first DIT/ANA caller who encounters a busy or no answer condition within a preprogrammed amount of
time will receive the first delay-announcement message from it’s beginning. After the message has been
played, the caller will hear music-on-hold (MOH). After a programmed amount of time, the caller will hear the
second delay announcement message. Upon completion’ of the second delay announcement message, the
caller will hear MOH. The caller will continue to be transferred between the second delay announcement and
MOH until someone in the UCD group answers the call.

PROCEDURE
NOTE
1:
Ensure that antistatic handling precautions are observed when handling the ECR-E ETU.
NOTE 2:
If the System Software is upgraded from Series 300, the input connection for the first announcement must
be changed to JK2 on the ECR-E ETU.
NOTE 3:
If system is operating with Series 300 software (allows only one Delay Announcement), JK3 on the ECR-E
ETU must be used.
6.1 Wiring connections to the ECR-E ETU from the System Frame Ground. (Refer to Figure 1)
6.1.1
Remove approximately 3 inches of outer insulation from both ends of the two lengths of 2-pair
Station cable. Strip off + inch of insulation from each of the eight wires.
6.1.2 Select a relay to be used (4-10) for Delay Announce. Use of relay 10 for the First Delay
Announcement and relay 9 for the Second Delay Announcement is recommended. Figure 1
shows the use of relays 10 and 9.
6.1.3
For the First Delay Announcement, connect one lead from one of the 4-conductor cables to the
System Frame Ground. Connect the opposite end of the same lead to the A side of the relay
chosen (A4 is recommended). Perform the same procedure for the Second Delay Announcement
(A3 is recommended) using another conductor from the same cable. Connections for relays 04-06
are located on the MDF and connections for relays 07-10 are located on the CNl terminal strip on
the ECR-E ETU.
6.2 RJ-31X Connection
6.2.1 Using the RCA male audio plugs and the audio shielded cable, make the following connections
between the ECR-E ETU and the RJ-31X Modular jacks. (See Figure 1.)
