When attached to the HST-3000 base unit, the DDS Local
Loop (DDS-LL) SIM lets you perform physical layer test oper-
ations necessary for provisioning transmission circuits. The
DDS-LL test option includes the following features:
– BER testing on all supported rates, including end-to-end
(straightaway) testing or loopback testing using another
test device at the far end.
– Channel service unit/data service unit (CSU/DSU) emula-
tion.
– A single 8-pin, RJ-48 DDS-LL interface connector. For pin
assignments, see
– Copper testing. See the HST-3000 Copper Testing User's
Guide.
– Frame Relay testing (optional). See the HST-3000 Frame
Relay Testing User's Guide.
Six status LEDs are located on the front of the HST-3000,
above the LCD screen.
