DS-0 synchronization over a wireless ATM link |
摘要 |
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.
