Table 7. H2TU-R DS1 Alarm Descriptions
Screen Alarm | Front-Panel Alarm | Description |
| | |
RLOS | RLOS | Remote Loss of Signal— Loss of the H2TU-R DS1 input signal. |
RAIS | RAIS | Remote Alarm Indication Signal—Indicates an AIS (all ones) pattern is being received at |
| | the H2TU-R DS1 input port. By default AIS-CI (a) is sent towards the network. |
RAI | RRAI | Remote RAI - Remote Alarm Indication at the H2TU-R—Indicates an RAI alarm (yellow) |
| | from the CPE with errors from the line unit or network. |
TX RAI-CI | TRCI | Transmit RAI-CI - Remote Alarm Indication at the H2TU-R—Upon reception of an RAI |
| | (yellow alarm) from the CPE, the H2TU-R sends a RAI-CI towards the network if the |
| | network signal received at the H2TU-R is clear. If the network signal is impaired (LOS, AIS |
| | or LOF), then the RAI is passed on to the network unaltered. This is applicable to SF or |
| | ESF framing. In an all SF environment, RACI must be enabled to convert SF RAI to SF |
| | RAI-CI. |
PRM-NE | PRMN | Performance Report Monitoring - Near End—The count of the PRM-NE register at the |
| | H2TU-R exceeds the 10-6BER threshold at 648 events since 12:00:00 AM. |
PRM-FE | PRMF | Performance Report Monitoring - Far End—The count of the PRM-FE register at the |
| | H2TU-R exceeds the 10-6BER threshold at 648 events since 12:00:00 AM. |
DBER | DBER | Bit Error Rate—The DS1 BER has exceeded the built-in 24-hour threshold limits of |
| | approximately 10-6. |
(a)AIS-CI is a modified AIS alarm pattern. Equipment not suited to detect AIS-CI still detects this signal as an AIS. AIS-CI is sent toward the network indicating that an LOS (RLOS) or AIS (RAIS) has been received from the CPE.
