ISDN Services
ISDN Services
Telex
Provides interactive text communication. It is the same as the existing Telex ser-
vice. The advantage of using it via ISDN is that it can be provided over an inter-
face shared with other services.
Message Handling System (MHS)
Allows you to send and receive electronic mail via a “post box”.
Supplementary Services
A Supplementary Service modifies or supplements a basic service. It may pro-
vide additional control functionality or provide information about an ISDN call.
Some of the Supplementary Services available are:
Multiple Subscriber Number (MSN)
Allows more than one number to be assigned to a line. Typically, a block of ten
numbers is assigned with the last number used to select the station.
Sub-addressing (SUB)
Allows you to specify extra addressing information in addition to the ISDN num-
ber.
Direct Dialing In (DDI)
Allows an ISDN station to call on an ISPBX directly without the operator.
User-to-User Signalling (UUS)
Allows you to send or receive a limited amount of information to or from another
station over the D-channel in association with an existing call.
Calling Line Identification Presentation (CLIP)
The called party can choose to be presented with the calling party’s ISDN num-
ber.
Calling Line Identification Restriction (CLIR)
The calling party can suppress the presentation of his ISDN number to the called
party.
Connected Line Identification Presentation (COLP)
The calling party can be presented with the ISDN number of the called party. It
tells the calling party who actually answers the call (for example if call forward-
ing is in operation).
Connected Line Identification Restriction (COLR)
The called party can suppress the presentation of his ISDN number to the calling
party.
Closed User Group (CUG)
Allows a group of users to appear to be in their own private network.
Terminal Portability (TP)
Allows a terminal to be unplugged from one socket on a Basic Rate Access con-
nection (S bus) and plugged into another socket on the same S bus without the
call being cleared.
Call Waiting (CW)
Gives notice of an incoming call even if all channels are occupied.
