Operation61181041L3-5A 7OPERATIONThe DS3-PSM serves as an ATM network interface. The ATM cells are packaged at the accessmodule and then either switched to another access slot or transported to the Wide AreaNetwork (WAN) where they are direct mapped into an unchannelized DS3 pipe. The DS3-PSMsupports 224 local subscribers out of a single 23-inch Total Access 3000 chassis or up to1344 subscribers with local subtending.Performance monitoring data is collected by both the working and protection DS3-PSM unitsand stored in local volatile memory. All required parameters listed in ANSI T1.231 aresupported.DiagnosticsThe DS3-PSM monitors DS3 line conditions for anomalies and/or Far End Alarm Channel(FEAC) codes in accordance with ANSI T1.107-1995. Alarm and status code words are trans-mitted by the DS3-PSM to the PCU for alarm processing when the specific alarm or statusconditions are met. The DS3-PSM provides the following test options:• DS3 Loopback Test• PVC/PVP Test• Single Card Cell Generation TestAlarmsLoss Of Signal (LOS) and Out Of Frame (OOF) detected on the incoming DS3 signal causes anAlarm Indication Signal (AIS) to be substituted in all low-speed tributaries.AISThe DS3-PSM inserts AIS in both the downstream and upstream directions. Downstream AISis inserted under any of the following conditions:• Activation of any tributary network loop• DS3-PSM is in an Out of Service-Unassigned state• During a T3 APS switch, the DS3-PSM going offline inserts a 32 msec burst of AIS to thelow-speed tributaries, forcing the access modules to switch to the new online DS3-PSM• One of the following RX conditions is detected:– LOS: Loss of T3 signal that is needed to supply the ATM tributaries– OOF: Out Of Frame condition exists on a signal needed to supply the ATM tributaries– RCV AIS: AIS is received on incoming T3 signal that is needed to supply the ATMtributaries– RCV Idle Signal: Idle signal is received on the incoming T3 signal that is needed to supplythe ATM tributariesUpstream AIS is inserted under either of the following conditions:• An assigned channel where the module is not supplying clock• Activation of Local Loopback on the DS3-PSM causes the transmission of T3 AIS towardthe network on the DS3 interface
