This line set differs from other IBM 3704 and 3705 line sets because it does not
include an external cable.
Line Set tK (CCITT V.3S Interface). For a description of this line set, see
"CCITT V.35 Interface" in this chapter.
This line set cannot be used if the type 1 communication scanner is installed on
the IBM 3704 and 3705.
Line Set 2A (Telegraph Single Current). This line set provides for the attachment
of two single-current leased telegraph lines that can operate at speeds up to 100
bps. Each line can be wired for...20 mA, 40 mA, or 62.5 mA single current termi-
nation.
Line Set 3A (Limited Distance Type 1 Line Adapter, 2-wire). This line set pro-
vides for the attachment of two start-stop lines at speeds up to 134.5 bps. The
line set includes two IBM Limited Distance Type 1 (2-wire) line adapters. No
external modems are required.
Line Set 3B (Limited Distance Type 1 Line Adapter, 4-wire). This line set pro-
vides for the attachment of two start-stop lines at speeds up to 134.5 bps. This
line set includes two IBM Limited Distance Type 1 (4-wire) line adapters. No
external modems are required.
Line Set 4A (Limited Distance Type 2 Line Adapter, 2-Wire). This line set
provides for the attachment of two start-stop lines at speeds up to 600 bps. The
line set includes two IBM Limited Distance Type 2 line adapters. No external
modems are required.
Line Set 4B (Leased Line Adapter, 2-wire). This line set pr_ovides
fot
the attach-
ment of two start-stop lines at speeds up to 600 bps. The line set includes two
IBM Leased Line (2-wire) line adapters. No external modems are required.
Line Set 4C (Leased Line Adapter, 4-wire). This line set provides for the attach-
ment of two start-stop lines at speeds up to 600 bps. This line set includes two
IBM Leased Line (4-wire) line adapters. No external modems are required.
Line Set SA (2400 bps Leased Line Integrated Modem, Point to Point--IBM 3705
only). This line set provides for the attachment of one synchronous leased line at
2400/1200 bps. The line set includes an IBM 2,400 bps, integrated modem with
receive equalization. No external modem is required.
Line Set SB (2400 bps Leased Line Integrated Modem, Multipoint Control--IBM
3705 only). This line set provides for the attachment of one synchronous leased
line at 2400/1200 bps. The line set includes an IBM 2,400 bps integrated modem
with no equalization. No external modem is required.
Line Set 6A (2400 bps Switched Network Integrated Modem--IBM 3705 only).
This line set provides for the attachment of one half-duplex synchronous switched
line at 2400/1200 bps. The line set includes an IBM 2,400 bps integrated modem
with automatic answering and automatic equalization. No external modem is
required. Line Set 6A is available only in the United States and Canada.
