relative equipment by attached connecting cable. Hot-swapping of V.35 sub card is forbidden and the
operation detail please refer to
“SUBM-FV35NX64K V.35 Interface Extend Module User Manual
REV.B”
Connecting Power Supply
Insert the attached 220V AC power cable to standard three phase power supply plug and at the same
time connect the -48V DC power cable to DC power connector (link device’s BGND connector to
power grounding, device’s -48V connector to -48V power and device’s PGND to earth). If the power
supply is +24V DC, please take above connecting method as a reference.
Power on Test
Link all needed cable and make sure they are connected well. Turn on the power and the PWR
indicator will be on and PWR1 and PWR2 indicators will be off.
Just after power on the device will perform initialization and self-check for at most 10 seconds.
During this process the ACT, 100M, FDX and LNK indicators will light circularly. Maybe LOF and
E-6 indicators of the optical port will flash once. These are all normal phenomena and after ten
seconds system will work normally.
Please make sure there are no alarms on optical port after the system works normally. If fiber is
connected correctly there will be no LOS, LOF, E-3 and E-6 alarms.
E1 Bit Error Test
Bit error rate of each E1 tributary can be test by 2M bit error rate tester cooperating with loop-back
dip-switches on front panel. For the testing method please refer to section 5 for operation
introduction.
Mask Dummy E1 LOS Alarm
If there is no Los alarm on connected E1 tributaries but the LOS alarm indicators of unused E1
tributary are on, so these alarms are called dummy E1 Los alarm. Set the Bit3 of SEL dip-switch as
on to mask local dummy alarms the relative E1 LOS alarm indicators will be off.
If disconnection occurs on linked E1 tributary, the LOS indicator of this tributary will be still on after
masking unused E1 alarm.
