Feature operation
To make a Flexible Hot Line Call, follow these steps:
1 Lift the handset. The Hot Line number is automatically dialed.
2 To end the call, hang up.
Enhanced Hot Line
Enhanced Hot Line (EHOT) provides Hot Line services to telephones with
programmable keys. This feature is designed for, and is compatible with,
analog (500/2500 type) telephones and Meridian 1 proprietary telephones.
All capabilities from Flexible Hot Line (HOT) are provided to any key/lamp
pair for one- and two-way Hot Lines on a per station basis. When the handset
is lifted, or when a preprogrammed key is activated, the system speed calls a
preprogrammed DN. Hot Lines access a set of terminal numbers programmed
by direct entry using LD 11, or by list entry such as by System Speed Call
(SSC) using LD 18. There is no difference in operation for the Hot Line user.
Once a Hot Line call enters the ringing state, it is the same as any normal call.
Enhanced Hot Line (EHOT) allows a distinction between analog (500/2500
type) telephone Hot Lines and manual Hot Lines without dial capabilities. For
example, telephones with EHOT enabled and dial facilities support Dial
Access features such as Call Transfer or Conference calling.
A Hot Line key can be defined with a Directory Number (DN) of its own,
allowing other calls to terminate on that HOT key. The DN must be defined
before it can be specified as the DN for a HOT key. For Meridian 1
proprietary telephones, the HOT key must be assigned to a DN during Service
Change to create a two-way Hot Line. Analog (500/2500 type) telephones are
always two-way Hot Lines, as they always have a DN assigned.
Operating parameters
Incoming calls to Hot Line telephones or keys can be restricted to calls
originating from other Hot Line telephones or keys, Voice Call keys, and
Group Call keys. This restriction is turned on or off on a per customer basis.
Telephones without a keypad or rotary dial cannot be assigned the Enhanced
Hot Line Allowed (EHTA) Class of Service.
