Appendix 5 - Glossary
V5.2 V5.2 interfaces consist of up to sixteen
2.048Mbps links, and support all access
types supported by V5.1 plus ISDN
Primary Rate access. A V5.2 interface is
required if Primary Rate ISDN is to be
supported. V5.2 supports the
concentration of bearer traffic, so that
the bearers on the user ports are
supported by a smaller number of
bearer channels on the interface. The
allocation of bearer channels to user
ports may change with each call, unlike
the allocation for a V5.1 interface.
V5 Interface This is the interface between an access
network and a host exchange for the
support of narrowband
telecommunications services. It allows
multiple access technologies to be
supported across a common interface.
The V5 interface has two forms: V5.1
and V5.2.
Video text Usually refers to an interactive
communication application in which a
user can communicate with a video
terminal.
Window The number of packets which can be
transmitted without acknowledgement
being received.
X.25 The packet switched data network.
