Description
[31:21] Reserved - None Must be set to zero
[20] Remote_loop R/W None When set, establishes a loop (per timeslot) between the
data received from the Ethernet port and the data
transmitted towards the Ethernet port.
Notes:
Usually the remote loop is activated on all timeslots
assigned to a bundle.
Only the TDM data is looped back. CAS information is not
looped back.
Available only when interface is configured to single clock
mode (Port[n]_cfg_reg.Two_clocks=0
).
[19] Local_loop R/W None When set, establishes a loop (per timeslot) between the
data received from the TDM port and the data transmitted
towards the TDM port. The data transmitted towards the
TDM port is delayed by one TDM frame vs. the received
data.
Notes:
Usually the local loop is activated on all timeslots
assigned to a bundle.
Only the TDM data is looped back. CAS information is not
looped back.
Available only when interface is configured to single clock
mode (Port[n]_cfg_reg.Two_clocks=0).
[18] Structured_type R/W Must be set for timeslots that are part of AAL1/CESoPSN
bundles whose type is structured or structured-with-CAS.
[17:16] Timeslot_width R/W None 00 = Reserved
01 =2 bits (only for HDLC bundles)
10 = 7 bits (only for HDLC bundles)
11 = 8 bits
See section 10.6.4 for additi
onal details.
[15] First_in_bundle R/W None Must be set for the first timeslot of an AAL1 or CESoPSN
bundle. Must be cleared for HDLC bundles.
[14] Rx_assigned R/W None 0 = timeslot is not assigned for the Rx path
1 = timeslot is assigned for the Rx path
[13] Transmit_assigned R/W None 0 = timeslot is not assigned for the transmit path
1 = timeslot is assigned for the transmit path
[12:7] Bundle_number R/W None Number of the bundle that the timeslot is assigned to.
[6:5] Reserved R/W None Must be set to zero
[4:0] Jitter_buffer_index R/W None Jitter buffer index. This field indicates which jitter buffer is
being used for the timeslot or bundle. It is also the index
into the Jitter Buffer Status Table (secti
on 11.4.8).
If a timeslot is assigned to a bundle, the jitter buffer index
must be configured to the number of the first timeslot
assigned to the bundle. Otherwise, it must be configured
to the timeslot number. See section 10.6.10.
