GPRS Trau frame encoder/decoder for Ericsson RBS
The Ericsson RBS BTS family is using a propritary TRAU frame dialect to
communicate with the GPRS/EGPRS part of their CCU. There are essentially
two implementations available:
- GPRS over 16kbps I.460 subslots (very limited, supports only CS1 and CS4)
- GPRS/EGPRS over full 64kbps timeslots (supports CS1-4 and MCS1-9)

+/*
+ * Idle pattern
+ * ============
+ * An inactive CCU will send an idle pattern, which is a sequence of alternating ones and zeros (101010101...) The
+ * idle pattern indicates that the CCU available but in idle state. To leave the idle state a channel activation
+ * via RSL must be carried out. It is not possible to "wake up" an idle CCU by just sending TRAU frames to it.
+ *
+ *
+ * Synchronization procedure
+ * =========================
+ * When the PDCH is activated, the CCU becomes active at its designated E1 timeslot/subslot. It sends out ccu_sync_ind
+ * frames and expects pcu_sync_ind frames from the PCU. When the CCU does not receive any pcu_sync_ind frames, the CCU
+ * becomes inactive until the PDCH is activated again.
+ *
+ * CCU is synchronized to the PCU by sending pcu_sync_ind frames with an incrementing PSEQ sequence number to the CCU.
+ * The PSEQ has no relation to the actual frame number. It just counts the TRAU frames sent over the E1 link. When
+ * the CCU receives a valid pcu_sync_ind it will synchronize its local PSEQ counter to the received PSEQ and respond
+ * back with a ccu_sync_ind that echos the PSEQ and also contains the current GSM frame numbers. The synchronization
+ * is then complete and the PCU may start sending pcu_data_ind.
+ *
+ * PCU CCU

+ * |<-------idle pattern---------|

+ * |--------pcu_data_ind-------->|
+ * |<-------ccu_data_ind---------|
+ *
+ * While pcu_data_ind and ccu_data_ind frames are passed over the link the PCU has no way to get the current PSEQ or
+ * any GSM frame number from the CCU. It must calculate those values locally. However, it is possible to request
+ * a ccu_sync_ind from the CCU at any time by setting the requested demodulation to ER_UL_CHMOD_VOID in one
+ * pcu_data_ind. It should be pointed out that the requested ccu_sync_ind will steal one pcu_data_ind. The requested
+ * ccu_sync_ind message will also only contain the GSM frame numbers but not the PSEQ value. If the GSM frame numbers
+ * in the received ccu_sync_ind are deviating from the local frame numbers, the synchronization procedure can be
+ * carried out again.
+ *
+ * PCU CCU

+ * |--------pcu_data_ind-------->|

+ * |--------pcu_data_ind-------->|

+ * |<-------ccu_sync_ind---------|
+ * |--------pcu_data_ind-------->|
+ * |<-------ccu_data_ind---------|
+ *
+ * It also should be mentioned that due to link latency, there will naturally be a gap between the PCU local PSEQ and
+ * the PSEQ reported by the CCU. This information is important since it must be used to compensate the GSM frame
+ * numbers.
+ *
+ * The procedure is very similar to what is described in US Patent No. 5,978,368 from Nov.2, 1999
+ *
+ * Usage of Timing Adjustment (TAV) parameter
+ * ==========================================
+ * The time adjustment is controlled by the CCU. The TAV value received in TRAU frames that originate from the CCU is
+ * the ordered timing adjustment. The TAV value in TRAU frames that originate from the PCU is the acknowledged time
+ * adjustment. When a timing adjustment is requested by the CCU, the PCU acknowledges it by sending the requested
+ * value back. The timing adjustment is performed immediately within the same frame by appending or removing bits
+ * at the end. This delays or advances the timing of the subsequent frame.
+ *
+ * The procedure is very similar to the one described in: GSM 08.60, section 4.6.1.2 */
