Serial Port and User Equipment Connection
Memotec 6-3
The HD-26 female connector automatically detects the interface and gender according to
the type of HD-26 custom cable that is installed. For example, with a V.35/V.11 DTE cable
the port will select V.35/V.11 electrical characteristics and DTE. Software configuration of
these characteristics is thus not required.
For details concerning the custom serial cable, refer to “Custom Serial Cable
Specifications” on page 6-5.
6.3 Connecting the User Equipment
To connect the user equipment to a 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 the SDM-8400 serial port.
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 System Reference for details.
6.3.1 Activating the User Equipment Connection
To activate the user equipment connection:
1. Configure all parameters and options for the connection. Refer to the NetPerformer
Reference Guides, which are included on the NetPerformer Documentation CD.
2. Activate a data connection by bringing up the connected user equipment.
3. Activate a voice connection by dialing a speed dial number to place a call.
4. Check the status of the NetPerformer, its connections and all active channels, ports,
PVCs and SVCs by executing the statistics commands (refer to the NetPerformer
Reference Guides for details).
