NOTE:
The 10BaseT and network connectors are not keyed. Follow the installation
procedures carefully to avoid connection errors.
"Procedure
To install the DSU/CSU:
1. Plug the 8-pin connector on the RJ48C network cable into the NETWORK
connector on the DSU/CSU.
2. Plug the other end of the RJ48C network cable into the RJ48C modular jack.
3. Plug one end of the 34-pin V.35 cable into the DTE port of the DSU/CSU.
4. Plug the other end of the V.35 cable into the DTE.
5. Insert one unkeyed 8-pin connector on the Ethernet cable into the 10BaseT
port.
6. Insert the other end of the cable into the Ethernet interface of the LAN where
your NMS resides.
7. Plug the 25-pin end of an EIA-232 cable into the TERMINAL port of the
DSU/CSU.

8. Plug the other end of the EIA-232 cable into either a VT100-compatible
terminal or PC.
9. Plug the end of the ac adapter into the POWER jack on the DSU/CSU.
10. Plug the ac adapter in an ac outlet.
11. Press Enter on the keyboard to display the Main Menu.
Using an External Modem
"Procedure
To connect an external modem instead of an asynchronous terminal or PC:
1. Use a standard serial crossover cable as shown in Figure 1 on the next page.
2. Enable auto-answer on your modem, and configure it to use standard
RS-232 detection and control for LSD, DSR, and DTR. Use the following
command string:
AT &C1 &D2 &S1 S0=1
Table 1. AT Command String
Command Description
&C1 Configures your modem to raise LSD after establishing a connection.
&D2 Configures your modem to drop connection when the DSU drops DTR.
&S1 Configures your modem to raise DSR when it begins to establish a
connection.
S0=1 Configures your modem to automatically answer incoming calls.

NOTES:
Your VT100 terminal or emulation software must be set to communicate at a
rate of 9.6 kbps, using characters of 8 bits, one stop bit, and no parity.
Verifying the connection to a LAN, router, or external modem requires setup
and configuration; see Chapter 3, Configuring the DSU/CSU, in the User’s
Guide.
