LOF (RED)—Powers up in the “off” state and illuminates when a LOF (Loss of
Frame) condition is detected on the incoming DS3. The LOF LED is off when the
signal is in frame. It reflects the LOF state of the DS3 in real time (no integration of
the state is needed).

LOCD (RED)—Powers up in the “off” state and illuminates when a LOCD (Loss of
Cell Delineation) condition is detected on the incoming DS3 under HEC (Header
Error Control) framing. The LOCD LED is off when delineations are obtained. It
reflects the LOCD state of the DS3 in real time (no integration of the state is
needed).

Figure 27 DS3 UNI Module LEDs
The DS3/E3 UNI shares the same queue (Queue 1) as the Group 1 IMA UNI;
therefore, if a DS3/E3 expansion card is installed in slot 9, the system deletes
Group 1 and all corresponding VCs on startup and generates an information only
alarm. Furthermore, you cannot add Group 1 if a DS3/E3 expansion card is
installed—either in the chassis or in the database. If you change the card type for
slot 9 to DS3/E3 via the List Card menu, Group 1 and the corresponding VCs are
not deleted until the system is restarted.

Step 5: Connect the
Management Terminal
In order to configure application connections and an IP address for SNMP support,
you must connect a management terminal to the PathBuilder S330/S310. To do
this, follow these steps:
you must connect a management terminal to the PathBuilder S330/S310. To do
this, follow these steps:
1 Connect a VT 100 terminal to the RS-232 (console) port on the front of the
PathBuilder S330/S310.
2 Use the VT100 terminal to input an IP address for the PathBuilder S330/S310. See
3 Establish communication between the PathBuilder S330/S310 and any
management terminal in one of these ways:
n
Direct RS-232 using the VT100 terminal or VT100 emulator, as described above
n
Direct 10BaseT on the Management CPU card using an IP Telnet session
