Page 26: Overview
Page 26 of 236 NTAK20 clock controller daughterboard Overview Digital trunking requires synchronized clocking so that a shift in one clock source results in an equivalent shift in all parts of the network. In the Succession Communication Server for Enterprise (CSE) 1000 system, synchronization is accomplished with an NTAK20 clock controller daughterboard located in each Media Gateway that contains a digital trunk card.
Page 27: Clocking Modes
Occasionally, environmental circumstances cause the external or internal clocks to vary. When this happens, the internal clock controller briefly enters the tracking Succession Communication Server for Enterprise 1000 Circuit Card Reference Guide...

If the incoming reference is unstable, the internal clock controller continuously tracks, and the LED continuously flashes green. This condition does not present a problem.
Page 29: Functional Description
A second PLL on the clock controller provides the means for monitoring another reference. Note that the error signal of this PLL is routed to the phase difference detector circuit so the microprocessor can process it.

Each line interface unit on the card has two jumper blocks that are used to select the proper loop current, depending on loop length. See Figure 53. For units connected to loops of 460 to 2300 ohms, both jumper blocks for that unit must have jumper straps installed.
