As long as the equipment on both sides of IPM equipment have the same framing, then there will be no alarms. However, the advantage of using framing (CESoPSN) is that the data bandwidth can be reduced considerably by sending only the payload, especially over a satellite link. You must make sure the right timeslots are enabled and match the crc4 if enabled or not (cesfe1crc). Duplicate these settings on both IPM4SE units. For the hex to timeslot bit mask, each TS is represented by a bit: TS bits : 11111111111111111111111111111111 TS # 33222222222211111111110000000000 31~0 10987654321098765432109876543210 If we breakup into octets, then we can assign hex values: 1111|1111|1111|1111|1111|1111|1111|1111 F | F | F | F | F | F | F | F So, if we want to enable fifteen timeslots, starting with TS1: 0000|0000|0000|0000|1111|1111|1111|1110 0 | 0 | 0 | 0 | F | F | F | E The cesfe1tsmap value would be x0000FFFE If the timeslot range always starts at TS1, this table will work for you: hex map no. of TS x00000002 = 1 x00000006 = 2 x0000000E = 3 x0000001E = 4 x0000002E = 5 x0000006E = 6 x000000FE = 7 x000001FE = 8 x000002FE = 9 x000006FE = 10 x00000FFE = 11 x00001FFE = 12 x00002FFE = 13 x00006FFE = 14 x0000FFFE = 15 x0001FFFE = 16 x0002FFFE = 17 x0006FFFE = 18 x000FFFFE = 19 x001FFFFE = 20 x002FFFFE = 21 x006FFFFE = 22 x00FFFFFE = 23 x01FFFFFE = 24 x02FFFFFE = 25 x06FFFFFE = 26 x0FFFFFFE = 27 x1FFFFFFE = 28 x2FFFFFFE = 29 x6FFFFFFE = 30 xFFFFFFFE = 31 21
