156 Clock Controller description and installation Introduction This chapter introduces the NTRB53 Clock Controller , and provides procedures on how to install this clock controller on Large Systems. The NTRB53 Clock Controller replaces the QPC471H and QPC775F in new systems.
Description 157 When only two switches are interconnected, synchronization can be achie ved b y operating the two systems in a master/slav e mode whereby one system derives its timing from the other .
158 Clock Controller description and installation ENL CC x FDL Enable Clock in side x with the force download option If the optional parameter is not specified, then downloading is conditional. This means that the v ersion number of the loadw are on the clock controller card will be chec ked against the v ersion number stored on the system disk.
Description 159 In an isolated pr ivate netw or k, the cloc k controller can oper ate in free run mode and act as a master clock to be track ed by other PBX systems in the pr iv ate network.
160 Clock Controller description and installation Stratum levels In a digital network, nodes are synchronized using a priority master/slav e method. Digital nodes are rank ed in Stratum lev els 1 to 5. Each node is synchronized to the highest r anking node in its neighborhood with which it has a direct link.
Description 161 A 1.5 Mb yte PRI contains a buff er large enough to hold about 2 full DS-1 frames (193 x 2 = 386). A 2 Mbyte PRI contains a b uffer large enough to contain 2 full frames (256 x 2 = 512 bits). The buff er is nor mally kept half full (1 frame).
162 Clock Controller description and installation While it is bey ond the scope of this discussion to provide detailed Network Synchronization, the follo wing e xamples illustrate some of the basic concepts to achie ve stable clocking.
Description 163 Figure 62 Example 3, Clocking Hierar chy referenced to a Public Network Master Clock This is an example of a "ST AR" arrangement— one Hub PBX is linked to the Central Office and all other PBXs are connected as slav es.
164 Clock Controller description and installation Figure 63 Example 4, Alternate Clocking from the same CO In this case, a digital connection to the Central Office can e xist (i.
Description 165 Figure 64 Example 5, digital connection to the CO In this e xample, digital connections to the Central Office do exist. When a second Digital loop from the CO becomes av ailable, it can be used as a Secondar y Clock Source in case the Primar y Source fails .
166 Clock Controller description and installation Figure 65 Example 6, Complex Isolated Private Network Digital connections to the Central Office do not exist in this example . If it does, the PBX connected to it will track off the CO and will in tur n be used as a clock source to other nodes.
Description 167 Figure 66 Example 7, Network Cloc king with MUX In this e xample, the direct connection to the CO (without a MUX) should be used as a primar y clock ref erence because this is where the least amount of hardware is in volv ed.
168 Clock Controller description and installation Free run (non-tracking) mode The clock synchronization f or a PRI loop can operate in free-run mode if: • the loop is not defined as the primar y o.

172 Clock Controller description and installation 4 Set the ENL/DIS toggle switch to DIS (disab le). 5 Replacing a clock controller , do the f ollowing: • P erf or m a status check on the clock with the SSCK command in LD 60. The new controller should hav e the same status.
Installation procedures 173 TRCK PCK (for primary) SCLK (for secondary) FRUN (for free-run) 14 Issue the status check command, SSCK. Note: In order for the clock enhancement f eature in the clock controller (NTRB53) to be fully functional, the user must issue a manual INI to activate the cloc k enhancement feature .
174 Clock Controller description and installation Note 2: ERR20 messages can be generated. These can usually be ignored. Howe ver , excessiv e clock s witching should be av oided, especially when counters are near the maintenance or out-of-ser vice thresholds.
Installation procedures 175 Upgrade to an NTRB53 Clock Controller on a Single Gr oup and Multi Group System F ollow these procedures to replace the existing cloc k controller with the NTRB53 Clock Controller on Large Systems. Note: The NTRB53 Clock Controller cannot be combined with a QPC775 or a QPC471 card in one system.
176 Clock Controller description and installation 4 Set the ENL/DIS s witch to DIS on the card you are removing. 5 T ag and disconnect the cables to the card y ou are removing. 6 Unhook the loc king devices on the card and pull it out of the card cage.
