Configurations (Terminals) lQ2Q £Qnt£Q! ftogel§, gng Feature§: The IBft 1050 Data Communication System is supported on either switched
or point-to-point nonswitched lines with these features: 1051 Control Unit (Model 1 or 2) with these features:
--Transmit Interrupt (17900) or Transmit Interrupt Control RPQ tE26903 --Receive Interrupt (16100) or Receive Interrupt Control RPQ tE27428
--Text Time-Out Suppression (19698) --First Printer Attachment (14408). This feature is required to
attach a 1052 Printer-Keyboard to the 1051. IBM 1052 printer-Keyboard (Model 1 or 2) with the PTTC/EBCD print
element (19571, Part 11167963) For switched lines, the Data Set Attachment (19114) is required. For point-to-point nonswitched lines, one of the following is
required:
--Data Set Attachment (19115 for facility Dl) -- or
--Data Set Attachment (19116 for facility B2)
-- or
--Data Set Attachment (19120 for facility Bl or Dl) or Line Adapter (14691-4694 for 4-wire shared nonswitched line)
or -- --IBM Line Adapter (14647 for 4-vire nonsvitched line)

The following control units can be locally attached on a byte
multiplexer, block multiplexer, or selector channel to support 3270 devices: 114 IBM VM/370 Planning and System Generation Guide
Configurations (Terminals) IBM 3272 Control Unit Model 2 for attachment of up to thirty-two 3277
Display stations Model 2, 3284 Printers Model 2, 3286 Printers Kodel
2, 3287 Printer Models 1 and 2, and 3288 Line Printers Model 2. To
support this configuration, the following are required:
--Device Adapter feature (13250) is required if more than 4 devices
are attached to the 3272. Up to 4 additional devices can be
attached with each device adapter.
--A 3271/3272 Attachment (18330) is required to attach each 3287 Printer. IBM 3274 Control Unit Kodel lB (supported as a 3272) for attachment
of up to 32 display stations and printers. All of the 32 devices can
be 3278 Display Stations Models 2, 3, and 41 (supported as 3277s),
3287 Printers Models 1 and 2, (supported as 3284s or 3286s), and 3289
Line Printers Models 1 and 2. (supported as 3288s). A maximum of 16
of the 32 devices can be 3211 Display Stations Model 2, 3284 Printers Model 2, 3286 Printers Model 2, 3281 Printers Models 1 and 2, and
3288 Line Printers Kodel 2. To support this configuration, the
following are required:
--The basic 3214 Control Unit permits attachment of up to 8 devices
(3278, 3287, and 3289). At least one 3278 is required.
--Each of the Terminal Adapter Types Al, A2, and A3 ('6901, 16902, and 16903) permits the attachment of up to 8 additional devices per
adapter (types 3218, 3281, and 3289). Only one of each type
terminal adapter is permitted. Terminal Adapter Type Al is a
prerequisite to Type A2, and A2 is a prerequisite to Type A3.
--Terminal Adapter Type Bl (#1802) permits the attachment of up to 4 additional devices (types 3277, 3284, 3286, 3287, and 3288). Only one adapter is permitted.
--Each of Terminal Adapter Types B2, B3, and B4 (t1803, #7804 and
#7805) permits the attachment of 4 additional devices per adapter
(types 3211, 3284, 3286, 3287 and 3288). Only one of each type
terminal adapter is permitted. Terminal Adapter Type Bl is a
prerequisite to Type B2, Type B2 is a prerequisite to Type B3, and
Tvpe B3 is a prerequisite to Tvpe B4. Terminal Adapter Tvpes Al and B3 are mutually-exclusive. ----- --A 327q/3276 Attachment (18331) is required for each 3287 Printer Models 1 or 2 that attaches to the basic 3214 Control Unit, or that
attaches to Terminal Adapter Types Al, A2, or A3. A 3271/3272
Attachment (#8330) is required for each 3287 Printer Model 1 or 2
that attaches to Terminal Adapter Types Bl, B2, B3, or B4. And only needed if a Type B adapter is used:
--Control storage Expansion feature (11801) provides the ability to
access control unit storage addresses above 64K.
--Extended Function Storage feature ('3622) provides additional
storage required to support particular attachments or
configurations. Control Storage Expansion feature (11801) is a
prerequisite.
lModels 3 and 4 are supported as Model 2 via hardware default. Part 1. Planning for System Generation 115
