How To Order


The WS1 is a wink-start adapter for channel bank Type 5 E&M ports. The WS1 is used when wink start is not supported on either the channel bank E&M board or the attached user equipment, but wink-start is required by equipment remotely connected via T1 or E1.

With wink start call processing, the E-lead out of the channel bank Type 5 E&M port goes off hook, closing a contact to chassis ground. In response to this E-lead change, the WS1 closes the M-lead for a few hundred milliseconds, then goes open. The momentary closure is a “wink”. The M-lead stays open for several seconds, during which time DTMF digits are typically sent out the channel bank over the receive pair audio leads, RJ45 pins 3 and 6. After the DTMF wait time, the M-lead closes and stays closed until the far end releases the E-lead, signaling on hook, the end of a phone call.

NOTE: The channel bank E&M port must be set for TYPE 5. The WS1 is wired for a straight through cable between the WS1 and a channel bank E&M card wired as B-side.

The left side RJ45 connector is for the channel bank E&M card. The local equipment connects to the right hand RJ45 connector. There MUST be an external wire from the channel bank chassis ground to PIN 1 on the 3-pin Power connector.



Straight through RJ to RJ wiring requires B-Side Type 5 E&M cards. See the additional detail above.
