Adjuncts can directly connect to one of the external ports on the Packet Gateway
circuit pack using a null modem or limited-distance modem. This is the preferred
method for connecting adjuncts located near the switch. Similar configurations
are used to connect to CMS, Message Server, and ISDN Gateway.
The RS-423 interface on the Packet Gateway circuit pack can be switched via
administered connection to any DCP Mode 2 digital endpoint on the switching
network. Similar configurations are used to connect to CMS, Message Server,
and ISDN Gateway. In this configuration, the BX.25 link is switched over the TDM
bus to a DS1 port and over a DS1 facility to another G3r switch. The Packet
Gateway can use only DMI Mode 1 on the TDM bus.
DCS systems that use ISDN-PRI signaling use a TN464 Universal DS1 circuit
pack and do not require a Packet Gateway.
Link-Associated Maintenance Objects
Each link is made up of a chain of several different maintenance objects. The
list
sys-link
and
status sys-link
commands can be used to identify the specific
components that make up a specific link. All X.25 links use the following MOs:
—PKT-INT
— The PPN PKT-BUS
— The PKT-BUS of the port network housing the packet gateway
—PGATE-BD
—PGATE-PT
Certain configurations may also use some of the following:
— TDM-BUS
—DS1-BD
— UDS1-BD
—TIE-DS1
— ISDN-LNK
— ISDN-TRK
When investigating link problems, first resolve any problems existing at higher
levels such as PKT-INT and PKT-BUS, and then proceed to problems at lower
levels such as ISDN-TRK.
