jack on the backplane of the rack, plug the telephone cord
into the RJ11 jack on the appropriate modem.
If you are connecting a -11L rack to leased lines or leased
lines with dial back-up, a Dial/Leased Splitter is required
between the leased line jack and the RJ11 jack on the
backpanel of the rack. The single RJ11 plug connects to
the RJ11 jackon the backpanel of the rack. The RJ11 jack
labeled Leased connects to the leased line connector. If
dial-back up is used, the RJ11 jack labeled dial should be
connected to the dial-back up line.
Note: The Dial/Leased Splitter is a custom part (a "Y"
cable) which includes an RJ11 plug that plugs into the
RJ11 jack on the backplane of the rack and is a 5-inch-
long six-conductor cable terminated at two RJ11 jacks.
One jack is labeled Leased and the other Dial.
