High-bandwidth functionality at low,
easy to manage prices
Our "Integrated Services Digital Network"
(ISDN) is used for a host of applications ranging from regular
phone calls, fax, to data transfer, and even videoconferencing,
providing services at transmission speeds of 128Kbps to almost
1.5Mbps.
HGC will install all the necessary equipment
required to connect you to the ISDN network, at our relatively
low local ISDN charge. Best of all, ISDN is charged on a per-usage
basis, so you pay only for the bandwidth you use.

Key Features
The 64Kbps B channels carry your voice,
video or data traffic, while the D channel is used by the
network to set up calls and monitor performance. Additionally,
a range of optional features are also available with our Basic
and Premium ISDN service packages. These include:
Advanced Voice Features
Abbreviated dialling, Call Waiting
and Call Forwarding to facilitate call management.
Calling Line Identification Presentation (CLIP)
Ensures that the called party can
see the telephone number of the caller. This works for both voice
and data calls and represents an added level of convenience
and security.
Multiple Customer Numbers
Allows up to two ISDN numbers to be
assigned to a single interface.
Sub-addressing
Allows individual numbers or a "sub-address"
to be set up so that messages (voice/video, mail/data) are
delivered quickly and transparently to each user or equipment
item connected to your ISDN line.
