ITU-T V.150.1

23 Receiver Symbol Rate Enable (RxSEN): Used if event ID has a value of 3. If set to a
value of 1, this parameter indicates that the optional receive symbol rate field (RxSR) is
being used in the message.
24:39 Transmit Data Signalling Rate (TDSR): Used if event ID has a value of 3. The locally
selected transmitter data signalling rate in bit/s. (0…65535). This is the same definition as
used in CONNECT (TDSR), (See Table 25).
40:55 Receive Data Signalling Rate (RDSR): Used if event ID has a value of 3. The locally
selected receiver data signalling rate in bit/s. (0…65535). This is the same definition as
used in CONNECT (RDSR), (See Table 25).
56:63 Physical Layer Transmitter Symbol Rate (TxSR): Used if event ID has a value of 3.
This optional field indicates the Gateway physical layer transmitter symbol rate. The
values are only valid if the TxSEN bit is set. The values in symbols/s for this field are:
0: Null (i.e., when a symbol rate is not applicable, e.g. V.21)
1: 600
2: 1200
3: 1600
4: 2400
5: 2743
6: 3000
7: 3200
8: 3429
9: 8000
10…254: Reserved for ITU-T; these values are not interpreted by a receiver
255: Unspecified
64:71 Physical Layer Receiver Symbol Rate (RxSR): Used if event ID has a value of 3. This
optional field indicates the Gateway physical layer receiver symbol rate. The values are
only valid if the RxSEN bit is set. This field uses the same set of values as described for
TxSR above.
15.4.9 Clear down indication (CLRDOWN)
This message may be sent to a remote Gateway to notify it of a local clear down event.
