If the Rx level is very low, it can trigger Loss of Signal Tx, or even Open Circuit tx. 10db->-12db, or -36fb, -44 db) Then check the cable or possibly replace it. If you notice your connection lower (i.e. Rx Level Signal strength of the connection between the Sangoma card and the other end. One or more incorrect bits in the alignment word This occurs when the CRC polynomial calculation performed before transmission does not match the CRC calculation done upon reception. Also, check line Framing (E1: CRC4 vs NCRC4) Possible reason are: line noise, corroded wires.etc. This means the other end of the line received bad data from you. Line Code Violation This occurs upon a bipolar violationįar End Block Errors is reported by the upstream end of the PHY (the wire between you and the switch) on the out-of-band management channel. A typical scenario would be mis-configuration during the Sangoma card configuration (i.e selected CRC4 vs NCRC4). When the equipment enters a Red-Alarm state, it returns a Yellow-Alarm back up the line of the received OOF. It is typical to have this alarm triggers in combination with 'Open Circuit' if there is an issue with the physical connection You will also see the Rx Level either very low, or in a disconnected state: -36 -> -44. Check the health of the cable plugged into the port, as well as its connection to the port it is plugged into. Product Details Manufacturer: Sangoma Model: A101-KIT UPC: 680031526115 SKU: 02-102021 MSRP Price: 702. If the only alarms indicating in the wanpipemon output is AIS:ON, then contact your telco with this information (RAI:ON can also be a possibility in this case as well)Įxample call diagram of the scenario: Sangoma card '-44'. all-ones signal transmission to the receiving equipment (the Sangoma card) to indicate that an upstream repeater (telco equipment) is in alarm, due to upstream transmission fault, either from another repeater or from the telco itself. (Alarm Indication Signal): typicall know as a BLUE Alarm. If RAI and AIS alarms are not indicated, verify that you have selected the proper line framing (i.e T1: ESF, D4, E1:CRC4, NCRC4.etc) Raised after four consecutive frames with FAS error. Sangoma IP phones are designed for the greatest interoperability with either.
