Configuring overlap receiving on PRI lines
Overlap receiving affects the procedure of establishing an incoming call received on a T1 or E1 PRI line in the TAOS unit. With overlap receiving, the TAOS unit can gather the complete called number from the network switch via a series of Information messages, enabling the use of features such as
Configuring clocking
You can configure the TAOS unit to use any of the E1 lines as a master clock source for synchronous connections for an entire system. In synchronous transmission, both the sending device and the receiving device must maintain synchronization in order to determine where one block of data ends and the next begins.
From the E1 lines configured as eligible clock sources, the TAOS unit chooses a clock source on the basis of priority. If multiple E1 lines are configured as eligible clock sources and have an equal clock priority, the TAOS unit chooses one of them at random. Once chosen as the clock source, the line is used until it becomes unavailable or a
If no eligible external sources are available, the system uses an internal clock generated from the primary shelf controller. Using the internal clock is generally not recommended.
