This section provides the pin number assignment and wiring information for the connectors on the
ExtendAir (TDD) Series radios. All connectors are shown as viewed from the radio rear panel,
oriented with the PoE connector at the lower left corner..
TDM Connections
There are two connectors for TDM; each connector has two TDM circuits available. Figure 47
illustrates the pin orientation and functionality of these connectors. These connectors are disabled on
the IP version radios.

RSL Sync Connector
This connector can be used during the antenna alignment process, to provide a received signal level
(RSL) voltage to a voltmeter. The connector is also used for connection to an optional Exalt GPS
antenna for the purposes of GPS synchronization, or used to send or receive sync signals to a
collocated radio, or to an ExaltSync Collocation Kit, for multiple radio sync. Figure 48 illustrates the
pin orientation and functionality for this connector.
