MULTIPOINT INSTALLATION
Only terminals designed for multipoint operations can be used in multipoint networks. The
multipoint options are 021, 027,028,038,047, and 048). Multipoint terminals are broken down
into first multipoint, daisy chain asynchronous, daisy chain synchronous, and DSN data link
terminals.
Table 7-4 lists the terminal multipoint capabilities according to option number.

The standard 2628A terminal cannot be used for multipoint operations.
Standard
Terminal
Option
Port 1 is used for connection to a DSN data link.
021
Option
HP first multipoint terminal, for use as the first terminal following the
027
modem in an HP multipoint (either asynchronous or synchronous) daisy
chain. Port 1 is the first multipoint connector.
Option
HP asynchronous daisy chain terminal, for use in an HP multipoint, asyn-
028
chronous daisy chain, in any position except the first following the modem.
Port 1 is the daisy chain connector.
Option
HP synchronous daisy chain terminal, for use in an HP multipoint,
038
synchronous daisy chain, in any position except the first following the
modem. Port 1 is the daisy chain connector.
Option
IBM first Bisync terminal, for use as the first terminal following the modem
047
in an IBM multipoint daisy chain. Port 2 is the Bisync connector.
Option
IBM daisy chain Bisync terminal, for use in an IBM multipoint daisy chain in
048
any position except the first following the modem. Port 2 is the Bisync
connector.
