Feature Key Guide

LD 11: Digital Stations

Telephone function key assignments determine calling options and features available to a telephone.

Some features are only allowed on specific keys, see M3900 Series Keys and/or 1120e Soft Keys for more info.
Some KEYs also require an associated CLS assignment to make the feature available to the user/telephone.

➤ A sets KEYs are printed/changed in LD 11 (or 20) as part of the stations TN block.

Syntax: KEY xx aaa yyyyWhere: xx = key number
aaa = feature
yyyy = parameter(s)

The Primary Directory Number (PDN) is always on Key 0: single or multi-call, ringing or non-ringing.

eg: KEY 00 SCR 4300 0 MARP - SCR = Single Call Ringing key, 4300 = the sets DN, 0 = CLID table entry
