I am working for intallation for RBS2206. Configuration is 4+4+4. But we are using 2 E1’s only!! As a single E1 has 2mb/s (in 32 time slots)bandwidth. 4+4+4 configuration means 96 time slots. How this information is multiplexed on only 2 E1s only? Logically shouldnt 3 E1’s (32 * 3 =96 timeslots)? Please clearify in detail..
