13.9 Cabling to an AT&T General Telemetry Processor (GTP)
The AT&T General Telemetry Processor is an E2A remote interface for discrete scan
points. Although all the devices covered in this document are able to support E2A on any
of its ports, the special requirements of the GTP limits its interface to the 9480 and the
4284 at this time.
The AT&T GTP presents a DB25 Female connector. The adapter used to connect to the
AT&T GTP is the standard asynchronous DCE with a DB25 male.
When a 9480 is used, it is connected directly to the AT&T GTP E2A remote without
special cabling, but with a DB25 male-to-male gender changer.
The configuration of the port is as follows:
Port <port num> type=orig prot=e2a
Port <port num> dest=<
E2AHOB IP Address> dport=< E2AHOB TCP Port>
Port <port num> dxe=dce swcar=on
Rs <port num>
Due to the nature of TNC to GTP traffic, the
E2AHOB is the only vertical service that
may be used to create the virtual bridge network. The IP-E2A application may not be
used for this function. This restriction applies only to AT&T GTP, the DPS NTP, and the
AT&T TNC endpoints.
