The RJ-11 connectors are located at the front panel of the TC8612.
2.7.3.1 Dry Contact Ports
For dry contact closure applications, the TC8612 can be used as either the Closure
Detector or Relay depending on which pins are used.
By default, the dry contact Relay will open when T1/E1 link is not in sync.
(Optional factory setting: Dry contact Relay will retain the last good state when T1/
E1 link is not in sync.)
• The Closure Detector side has a dry contact closure detector.
• The Receiver side has a dry contact Relay.
The Close or Open status is controlled by a relay switch inside the card. It reflects
the remote detector's status. The virtual pin connections allow the TC8612 to be
used as either a closure detector or a dry contact relay. (See
Dry Contact Closure
Detector,
on page 2-7)
• The RJ-11's pins 4 and 5 are closed at the closure detector side, the status is
reflected at the remote relay side of the RJ-11's pins 2 and 3.
• The Relay switch is rated 1.5A DC maximum switching current with a
maximum voltage of 60 VDC. (See
Specifications,
on page 1-5.)
