Table 171 TDM Configuration attributes
Attribute Meaning
TDM Interface Control Display only. Defined in Table 154 .
TDM Local MAC Address Display only. MAC address of the local NIDU.
TDM Remote MAC
Address Display only. MAC address of the remote NIDU.
License Max Number of
TDM Channels Display only. Defined in Table 154 .
TDM Enabled Channels Display only. Defined in Table 154 .
TDM Channel Line Code
n Defined in Table 154 .
TDM Channel Cable
Length n Defined in Table 154 .
TDM Channel Loopback
n Select the loopback status of TDM channel “n” (where “n” is in
the range 1 to 8).
None: Normal operation, no testing is required.
Copper: Sends the TDM data received from the local transceiver
and NIDU back on the same TDM channel. This may be used in
conjunction with a Bit Error Rate Tester to confirm that the
correct connections have been made between the transceiver,
NIDU and ODU. This mode cannot be used for resistance tests,
as it is only capable of looping back valid TDM signals.
Wireless: Sends the TDM data received from the wireless link
back across the link on the same TDM channel. The link may be
checked using, for example, a Bit Error Rate Tester to ensure
that no errors are detected.
Lowest TDM Modulation
Mode Display only. Defined in Table 154 .
Authorization Control page
Menu option: System > Configuration > Authorization Control ( Figure 161 ).
Authorization control is used when Access Method is configured to Group Access, and
Encryption Algorithm is configured to TLS-RSA. In the HCMP topology, Group Access is the
only Access Method supported. In the PTP topology, Group Access is available only with the
Group Access license. The Authorization Control page is hidden if it is not applicable.
When Authorization Method is configured to Whitelist, the ODU will connect only if the
authenticated MAC address of the remote unit is in the list of authorized ODUs. With the
Blacklist option, the ODU will always connect unless the authenticated MAC address has been
added to a list of unauthorized ODUs.
The Authorization Control page allows up to 32 MAC addresses to be entered.
