Toolpack v2.3:BITS Ports
TelcoBridges Tmedia and Tdev devices support the sharing of a precision clock among multiple devices via the Building Integrated Timing Supply (BITS) method. With TelcoBridges hardware, BITS Ports are derived from DS3 and STM-1 TDM adapters of a Tdev TMP6400 or a Tmedia TMG3200, as well as from a TMS1600. The BITS clock source must support the kbits/s mode (not kiloHertz/kHz mode).
BITS ports and clocking
In order to use BITS as a clocking source, the BITS ports of a TDM module are assigned to a line service that will carry the BITS port signaling. BITS Ports are shown in the figure below.

Using BITS ports for signaling
Starting with release 2.3 of Toolpack, it is possible to convert unused BITS ports into signaling ports in order to recover a channel on the primary DS3 or STM-1 connection. Note that CAS protocols (R1 and R2) will not work on BITS ports used in signaling mode.
