To connect the user equipment to the serial port:
1. Locate the HD-26 custom cable that is appropriate for:
- The device you are attaching: DTE or DCE
- The interface you want to use: V.35/V.11, TIA-232 (V.24), X.21, X.21 EU,
TIA-449 (V.36) or TIA-530.
2. Connect the male end of the HD-26 cable to a serial port on the SDM-9220/9230.
3. Connect the other end of the cable to the user device (CSU/DSU, modem, router,
front end processor, etc.).
CAUTION:: Do not connect a data port (WAN/user) to a host, PU,
or Frame Relay device until you have configured the port protocol
via the software. Refer to the NetPerformer Reference Guides for
details.
5.3.1 Activating the User Equipment Connection

Reference Guides, which is included on the NetPerformer Documentation CD.
2. Activate a data connection by bringing up the connected user equipment.
