1.
A 3708 DCE cable connects a 3708 to a modem, a modem eliminator, or a null
modem. A 3708 DTE cable directly connects a 3708 to a host or an end-user
device.
2. The IBM EIA 422A cables can only be used with an IBM 3101, an IBM 3151,
an IBM 3161, an IBM 3162, an IBM 3163, an IBM 3164, or a compatible
terminal.
3. Cable PN 6405397 contains surge-suppressing diodes.
4. Variable-length cable is available only in the USA and A/FE countries. See a
marketing representative for the availability in your country.
5. The fixed-length cable PN 6405398 is available only in EMEA countries. See
the marketing representative for the availability in your country.
