Isdn Data Call Requirements - EMS HSD series User Manual

ISDN data call requirements

The following equipment is required to make an ISDN
connection using a HSD Transceiver:
Bonded calls (two-channel systems only)
Bonded calls are possible with HSD transceivers that have
two channel cards installed. Bonded calls utilize both 64 k
channels to provide a single 128 k data channel. The
terminal adapter or router places two separate calls to
combine the data transfer over both channels.
Although bonded calls provide a single 128 k channel, the
actual link capacity is application and protocol dependant.
Typical throughput on a Multilink PPP TCP/IP connection
is only 80 to 90 % of the link capacity (running Windows
2000).
The system can only make bonded calls if both channels are
available. If another device is using one of the B Channels,
then the data call proceeds—but as a single channel call.
If a bonded call is in progress, (using both B channels) the
system is busy and denies all other calls until a channel is
free.
