2.5 Appendix 1 - 2Mbit/s Frame

basic frame

▼ The synchronous 2048 Kbit/s signal is structured on a 256-bits frame, numbered 1 to 256; it is composed by 32 time slots (TS), numbered 0 to 31 (TS0 to TS31), each time slot containing 8 bits. The frame repetition rate is 8000 Hz (time period 125 ms).

▼ TS0 is used as the OverHead of the frame, for purposes as: frame alignment, error integrity check, messaging, etc.

▼ The following figure shows the allocation of bits 1 to 8 (i.e. Time Slot 0, TS0) in the basic frame structure of synchronous 2Mbit/s signal.

▼ The frames contain, alternatively, the 7-bits frame-alignment-signal (FAS = 0011011, bits 2 to 8). (ITU-T G.704)

Note 1 - Si = bits reserved for international use. One specific use is for multi-frame alignment and for CRC-4

procedure.

Note 2 - this bit is fixed at 1 to assist in avoiding simulations of the frame alignment signal.

Note 3 - A = Remote Alarm Indication (RAI). In undisturbed operation, set to 0; in alarm condition, set to 1.

Note 4 - Sa4 to Sa8 are used for point-to-point specific messaging.



2 - 2 - 35

Note 1 - E = Remote Error Indication (REI) .In undisturbed operation, set to 1; in alarm condition, set to 0.

Note 2 - Sa4 to Sa8 are used for point-to-point specific messaging.

Note 3 - C1 to C4 = Cyclic Redundant Check-4 bits.

Note 4 - A = Remote Alarm Indication (RAI).In undisturbed operation, set to 0; in alarm condition, set to 1.

Note 5 - MF1 to MF6 = Multiframe Alignment Signal (MAS = 001011).


CRC-4

� The following figure shows the allocation of bits 1 to 8 (i.e. Time Slot 0, TS0) in the CRC-4 multiframestructure of synchronous 2Mbit/s signal. CRC-4 is the abbreviation for Cyclic Redundant Check-4, a signal elaboration procedure to check the error integrity.

� Each CRC-4 multiframe, which is composed of 16 frames numbered 0 to 15, is divided into two 8-frame sub-multiframes (SMF), designated SMF-I and SMF-II which signify their respective order of occurrence within the CRC-4 multiframe structure. Each sub-multiframe duration is 1 ms, rated 1000 Hz. The SMF is the CRC-4 block size (i.e. 2048 bits).

� Refer to ITU-T G.704 rec. for details information.

ISDN-PRA

▼The ISDN-PRA (Integrated Services Digital Network - Prim ary Rate Access) is a facility to carry a number of synchronous digital communication channels to the user over a 2048 kbit/s structured signal; the ISDN- PRA structure is defined in recommendation ETS 300 233.

▼Organization of ISDN - PRA frames

� For each direction of transmission the following functions are provided by the

synchronous ISDN-PRA 2048 Kbit/s frames (refer to recommendation ETS 300 233):

�30 time slots at 64 kbit/s (numbered 1 to 15 and 17 to 31) for the transport of any

appropriate allocation of the B, H0 and H1 channels.

�1 time slot at 64 kbit/s (numbered 16) for the transport of a D channel.

�1 time slot at 64 kbit/s (numbered 0) for frame alignment, multiframe alignment,

CRC-4 procedure and maintenance (rec. G.704)

ISDN-PRA

▼ISDN - PRA communication channels

� The communication channels transported by the ISDN-PRA (Integrated

Services Digital Network - Primary Rate Access) signal are the following:

�B-channel it is rated 64 kbit/s, as defined in ITU-T Rec. I.412; it permits the

allocation of up to 30 independent B-channels over the 2Mbit/s synchronous frame.

�H0-channel it is rated 384 kbit/s, as defined in ITU-T Rec. I.412; it permits the

allocation of up to 5 independent H0-channels over the 2Mbit/s synchronous frame.

�H1-channel it is rated 1920 kbit/s, as defined in ITU-T Rec. I.412; it permits the

allocation of one H1-channel over the 2Mbit/s synchronous frame.

�D-channel it is rated 64 kbit/s, as defined in ITU-T Rec. I.412.
