Caution
The lower center frequency attribute must be configured to the same value for both
the Master and Slave, otherwise the wireless link will fail to establish. The only way to
recover from this situation is to modify the Lower Center Frequency attributes so that
they are identical on both the master and slave units.
Note
When configuring a linked pair of units, use the Master Slave Mode to ensure that one
unit is Master and the other is Slave.
Table 155 Wireless Configuration attributes
Attribute Meaning
Master Slave Mode Master: The unit controls the point-to-point link and its maintenance. On
startup, the Master transmits until a link with the Slave is made.
Slave: The unit listens for its peer and only transmits when the peer has
been identified.
Access Method ODUs must be configured in pairs before a link can be established. Access
Method determines how paired ODUs will recognize each other.
Link Access: Each ODU must be configured with Target MAC Address
equal to the MAC Address of the other unit.
Link Name Access: Both ODUs must be configured with the same Link
Name.
Group Access: Only displayed when a Group Access license key has been
generated (
Generating license keys on page 6-3 ) and submitted ( Software
License Key page on page 6-13 ). Both ODUs in a PTP link, and all ODUs in
an HCMP sector, must be configured with the same Group ID attributes.
Group Access is the only Access Method supported in the HCMP
topology.
Target MAC Address Only displayed when Access Method is set to Link Access. This is the
MAC Address of the peer unit that will be at the other end of the wireless
link. This is used by the system to ensure the unit establishes a wireless
link to the correct peer. The MAC Address can be found embedded within
the serial number of the unit. The last six characters of the serial number
are the last three bytes of the unit’s MAC address.
Link Name Only displayed when Access Method is set to Link Name Access.
Link Name may consist of letters (A-Z and a-z), numbers (0-9), spaces, and
the following special characters: (),-.,:<=>[]_{}
Link Name must be same at both ends and different to site name.
Group Id Only displayed when Access Method is set to Group Access. A link can
only be established between units that have identical Group IDs.
Dual Payload Disabled: The link maximizes robustness against fading and interference.
Enabled: The link attempts to reach maximum throughput at the expense
of robustness against fading and interference.
