Loop Keys
Description
Loop keys are uniquely programmed function keys that simplify placing and answering trunk calls.
There are three types of loop keys: Incoming Only, Outgoing Only and Both Ways.
Incoming Only Loop Keys
Incoming Only loop keys are for answering trunk calls. An extension can have an incoming loop key
for a specific trunk group (fixed) or a “catch all” loop key for any trunk group (switched). Fixed loop
keys allow an extension user to tell the type of call by the ringing key. Switched loop keys are ideal for
an extension with a large number of feature keys. In addition, switched loop keys are a destination for
any trunk not on a line key or fixed loop key. Incoming Only loop keys also receive Transferred trunk
calls.
Outgoing Only Loop Keys
Outgoing Only loop keys are for placing trunk calls. An extension can have outgoing loop keys for a
specific trunk group or for ARS access. When a user presses the loop key, they get dial tone from the
first available trunk in the group (or from ARS if programmed). Outgoing Only loop keys help ensure
that an extension will always have a key available for placing calls.
Both Ways Loop Keys
Both Ways loop keys combine the functions of both Incoming Only and Outgoing Only loop keys. Both
Ways loop keys work well for extension users that handle a moderate amount of calls and don’t
separate keys for incoming and outgoing calls. Both Ways loop keys also receive Transferred trunk
calls.
An extension can have many loop keys - of any type. You can program an operator, for example, with
four loop keys for incoming calls and four for outgoing calls.
Once a loop key call is set up, the user can handle it like any other trunk call. For example, the user
can place the call on Hold, Transfer it to a co-worker or send it to a Park Orbit.
An incoming call will ring the first available loop key, beginning with the lowest numbered key. If keys
1-3 are loop keys, for example, the first incoming call rings key 1. If key 1 is busy, the next call rings
key 2. If keys 1 and 2 are busy, the next call rings key 3. If all three keys are busy, additional incoming
calls queue for the first available key. The terminal display will show “WAITING - LOOP KEY” if the
user presses a loop key when there are additional calls waiting.
Conditions
When a station is talking to a caller on a loop key, and a second DID or DIL call rings the users phone,
the outside caller will be connected when the user presses
Hold key. If the second call to the phone
was via a ring group, the outside caller would not be automatically connected when the user presses
Hold key, the user would then have to press the loop key to be connected.
