Figure 5.12 Serial 1 and 2 Configuration Menu Tree
Type This parameter selects the type of interface (based on its electrical signal
characteristics) used by the equipment connected to the Serial port.
Values: V.35, RS-232, EIA-530
Default: V.35
NOTICE: V.35 requires the use of an optional cable. Refer to Appendix A,
“Specifications,” for ordering information.
Mode By default, the Serial port serves as a DCE port in both Packet and TDM
modes. However, the Serial port can serve as a DTE port when the unit is in
Packet mode.
If the Serial port connects to a DTE device (such as a FRAD or a router), the
Mode parameter must be set to “DCE.” If this port connects to a DCE device
(such as a DSU/CSU), this parameter must be set to “DTE” (valid only for
Packet mode, not TDM).
Values: DCE, DTE
Default: DCE
