Type 1 Teleprocessing Communication Adapter
The Type 1 Teleprocessing Communication Adapter provides EIA 232D/CCITT V.24
and
CCITT V.35 interfaces
for
SNA/SDLC, SSC,
or
X.25 remote
link
attachment to
the host. The adapter
is
optional on models 1
L,
11
L,
3R,
and 13R. It
is
a base
feature on these models: 1
R,
11
R,
51
R,
61
R,
81
R,
and
91
R.
With the adapter
installed and with
appropriately
configured
microcode
loaded, the 1
L,
11
L,
3R,
and
13R can operate on teleprocessing
facilities
as
either
model 1 R
or
11
R.
Type 2 Teleprocessing Communication Adapter
The Type 2 Teleprocessing Communication Adapter provides
X.21
interface (CCITT V.11)
for
SNA/SDLC
or
X.25 remote
link
attachment to the
host. The adapter is optional on models 1
L,
11
L,
3R,
and 13R. It
is
a base feature
on these models:
2R,
12R, 52R, 62R, 82R, and 92R. With the
adapter
installed and
with
appropriately
configured
microcode
loaded, the 1
L,
11
L,
3R, and 13R can
operate on teleprocessing
facilities
as
either
model
2R
or
12R.
4Mbps Type 3 Communication Adapter
This
adapter provides the
ability
to operate on an ISM Token-Ring at 4Mbps. It is a
base feature on models
3R
and 53R. It is an optional feature on
models
1
L,
1
R,
2R,
51
R,
and 52R. This adapter enables these
controllers
to act as
models
3R
or
53R
for
Token-Ring Network communication. (See
"Table
of
Alternate
Controller
Configurations" on page A-8
for
a table showing which
models
convert
to
which
models.)
If the Token-Ring Gateway feature
is
ordered, this
adapter
comes with
the feature.
It can also be
ordered
