Equipment Alarms Backward Alarms A feature exists that allows the user to Mask out certain alarms as explained below Alarms that are recorded in the event buffer are the same as the alarm buffer A CAUTION Masking alarms may cause undesirable modem performance When an alarm is masked the Front Panel LEDs and the Fault Relays do not get asserted but the Alarm will still be displayed This feature is very helpful during debugging or to lock out a failure of which the user is already aware 6 1 2 1 Active Alarms 6 1 2 1 1 Major Alarms Major Alarms indicate a modem hardware failure Major Alarms may flash briefly during modem configuration changes and during power up but should not stay illuminated Alarms are grouped into Transmit and Receive Alarms Transmit and Receive are completely independent 6 1 2 1 2 Minor Alarms Minor Alarms indicate that a problem may persist outside the modem such as loss of Terrestrial Clock loss of terrestrial data activity or a detected transmit or receive AIS condition Alarms are grouped into Transmit and Receive Alarms Transmit and Receive are completely independent 6 1 2 1 3 Common Equipment Faults Common equipment faults indicate hardware or configuration problems in the modem that effect both transmit and receive operation Most common faults indicate a hardware failure within the modem such as a bad power supply Common faults for the External Reference and Exte

T1 E1 Time Slot Since the D amp I Functions are separate and distinct two separate maps must be configured at the start of the D amp l Multiplexer Operation These are the Tx transmit Active Map for Drop Mapping and the Rx receive Active Map for Insert Mapping The number of entries in each map is determined by the data rates selected Each map entry consists of an IBS Time Slot assignment and the Terrestrial T1 or E1 Channel Number to which it is assigned Drop Mapping and Insert Mapping are completely separate and independent The map that is actually used for the Drop Function is the Tx Active Map the map that is actually used for the Insert function is the Rx Active Map Two additional maps exist the Tx Edit Map and the Rx Edit Map The Edit Maps are the buffer areas that are used when creating or modifying a map through the modem s VFD when editing is complete the appropriate map should be copied to the Active Map Any map may be copied to any other map with the exception of the ROM maps These maps may only be the source of the data used to create a User Edit or Active Map Maps can be created in the map editor and stored as User Maps New Active Maps can be downloaded during Modem Operation but this will result in a temporary disruption of service on the terrestrial line or the Satellite transmission TM110 Rev
