Connecting the 10/100Base-T Ethernet port to an Ethernet-capable workstation
The 10/100Base-T Ethernet port can connect to a single Ethernet-capable workstation by means of a cross-
over cable. Refer to
figure 10 to assemble a cross-connect cable that will connect between the NIC Ethernet
port in the workstation and the RAS 10/100Base-T Ethernet port.

Connecting the EIA-561 RS-232 configuration port
Install the supplied DB-9-to-RJ-45 cable between the RAS RS-232 port (see figure 8 on page 23) and an open
serial port on your computer. If you need to assemble your own cable, refer to the pinout diagram in figure 11.

Connecting to the T1/E1/PRI WAN ports
An active T1/E1/PRI is not necessary to configure the RAS. However, an active T1/E1/PRI connection is required
to receive or make calls. The factory-set default configuration of the access server has the T1/E1 ports disabled.
Note
The cable connecting the T1/E1/PRI WAN ports to the RJ-48C ter-
mination jack should be CAT-3 or higher and extend no farther than
1 mile (1.6 km) from the digital services termination.
