5.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 UC0 group answers the call.

6.PROCEDURE

NOTE 1: Ensure that antistatic handling precautions are observed when handling the ECR-EETU.

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)

6.1.1Remove 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.

6.1.3For 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.
