A system and method for the transmission of synchronization information from a wireless asynchronous transfer mode (ATM) base station across a point to point or point to multipoint wireless link, to one or more network interface units (NIUs). Each of the NIUs is capable of supporting a combination of structured or unstructured T1 and/or E1 circuit emulation services. The technique involves locking the wireless modem downstream symbol clock to an externally provided frequency reference from the base station. The reference is an N integer multiple of 8 kHz which is the lowest common denominator for both the T1 and E1 clocking rates.

DS-0 synchronization over a wireless ATM link

A radio interface card for use in a base station of a broadband wireless ATM system to support bi-directional communications with customer premise network interface units (NIUs) over a wireless link. The ATM radio interface card (ARIC) includes a modem for modulating data received from an ATM backbone connected to the base station into a point to multipoint format for transmission over the link to the NIUs. A demodulator in the ARIC supports a point to point protocol for processing digital communications received from distributed NIUs located within a geographic area.
