Connect Shelf to the X.25 Network
INTRODUCTION
This procedure provides step-by-step instructions to connect a MX2820 shelf to the X.25
network. The MX2820 system can send and receive Transaction Language 1 (TL1) commands
over an X.25 network. The System Controller Unit (SCU) has a built-in X.25 PAD, and the
shelf is ready to connect to the X.25 network via a DB-25 connector. Access to the network is
via an RS-232 port labeled, NTWK MGMT.
PREREQUISITE PROCEDURES
Obtain all necessary local instructions before proceeding with the MX2820 shelf installation.
The MX2820 shelf should be mounted in its permanent location in the Central Office (CO)
before connecting the shelf to the X.25 network.
MATERIALS REQUIRED
• DB-25 data cable with male connector on one end of the MX2820 shelf
• An appropriate connector to connect the X.25 switch or other X.25 equipment on the
opposite end. The connector needs to be of sufficient length to reach from the MX2820
backplane to the X.25 equipment and tied down in accordance with Central Office (CO)
Standard Operating Procedures (SOP).
WARNING
To prevent electrical shock, do not install equipment in a wet loca-
tion or during a lightning storm.
CAUTION
Electronic modules can be damaged by static electrical discharge.
Before handling modules, wear an antistatic discharge wrist strap
to prevent damage to electronic components. Place modules in
antistatic packing material when transporting or storing. When
working on modules, always place them on an approved antistatic
mat that is electrically grounded.
