framed» mode);
for the V.35/RS-530/RS-232/X.21 port: loss of ETC synchronization;
for the Ethernet 10/100Base-T port: packets checksum errors or loss of packets
because of insufficient throughput of the channel.
• «Event» – for the E1 link: overruns or underruns of controlled slip buffers;
for the V.35/RS-530/RS-232/X.21 port: FIFO data errors;
for the Ethernet 10/100Base-T port: collisions.
The Status column shows channels state as a set of flags.
The flags available for the E1 link are as follows:
• «Ok» – normal state, frame synchronization is Ok.
• «LOS» – loss of signal.
• «LOF» – loss of frame synchronization.
• «SLIP» – controlled slip.
• «AIS» – alarm indication signal (the «all ones» code) is being received.
• «LOMF» – loss of CAS or CRC4 multiframe synchronization.
• FARLOF – loss of frame synchronization at the remote device.
• «AIS16» – signalling alarm indication is being received (alarm indication signal re-
ceived in timeslot 16).
• «CRCE» – CRC4 error.
• «RDMA» – remote alarm (the A bit of the timeslot 0).
• «Test Ok» – BER tester is enabled, no errors detected.
• «Test Error» – BER tester is enabled, there are errors.
The flags available for the digital port are as follows:
• «Ok» – normal state.
• «No carrier» – loss of carrier.
• «No cable» – no cable connected.
• «No DTR» – DTR line is off (for the V.35/RS-530/RS-232/X.21 port only).
• «Passive» – the port is disabled because of loss of signal or loss of frame synchroniza-
tion in the E1 link.
