lpE1LineType 1.3.6.1.4.1.562.2.4.1.12.8.10.1.1

This attribute specifies the framing of the E1 line. When cas (channel associated signalling) is selected, timeslot 16 is reserved for multiframe signalling and only 30 timeslots are available for data. The signalling bits are not interpreted. When ccs (common channel signalling) is selected, timeslot 16 is not reserved for multiframe signalling and 31 timeslots are available for data. The signalling bits are not interpreted. When unframed is selected, a clear channel is defined whereby data from all timeslots including the framing data (in timeslot 0) and timeslot 16 are passed transparently. This value is valid only for AAL1 cards. For cell-based cards the ATM Forum specifies that timeslot 16 be reserved, leaving 30 timeslots available for data. The default value is cas except for the 8pE1Atm card, for which the default and only valid value is ccs.
