CHP. A single interface between a central processor and one or more
control units, along which signals and data are sent to perform I/O
requests (D).
CHPID. In a channel subsystem, a value assigned to each channel
path of the system that uniquely identifies the path (D). See also
channel-to-channel.
CSS. A collection of subchannels that direct the flow of information
between I/O devices and main storage, relieve the processor of
communication tasks, and perform path management functions (D).
CTC. A channel attached to another channel (channel-to-channel) and
specifies the I/O mode of operation for the channel path under the
I/O configuration program (IOCP) channel path identifier (CHPID)
statement 'Type' parameter (D). See also
A diagnostic procedure that checks S/390 host-to-director or
host-to-switch connectivity by returning the output of the host as
input. The test is host-initiated and transmits Fibre Channel frames to
a director or switch port. A director or switch port enabled for
channel wrapping echoes the frame back to the host.

Challenge Handshake Authentication Protocol (CHAP) provides a
type of authentication between an agent (typically a network server)
and the client program. Both share a predefined secret, which they
verify during an authentication login sequence. CHAP is used with
RADIUS servers to provide access authentication and accounting.

Used by switches to communicate across interswitch links (ISLs) to
configure, control, and coordinate a multiswitch fabric.
Defines the level of connection dedication, acknowledgment, and
