ISDN Primary Rate Interface equipment overview Echo canceller interface Echo cancellers are required only on satellite transmission circuits. The echo canceller detects the length of the loop, and then cancels out reflected transmission. (Callers will not hear echoes of their own voices reflecting back to them from the far end of the call.) The echo canceller’s control protocol must conform with that of the Tellabs Model 251.
NT8D72 PRI2 29 Figure 6 Clock controller primary and secondary tracking Free run (non-tracking) mode The clock synchronization of the system can operate in free-run mode if: • no loop is defined as the primary or secondary clock reference, • the primary and secondary references are disabled, or • the primary and secondary references are in local alarm Reference clock errors The system software checks at intervals of 1 to 15 minutes to see if a clock controller or reference-clock error has occurred.
ISDN Primary Rate Interface equipment overview A reference-clock error occurs when there is a problem with the clock driver or with the reference clock at the far end. If the clock controller detects a reference-clock error, the reference clocks are switched. Automatic clock recovery A command for automatic clock recovery can be selected in LD 60 with the command EREF. A PRI loop is disabled when it enters a local-alarm condition. If the local alarm is cleared, the loop is enabled automatically.

ISDN Primary Rate Interface equipment overview Tracking mode In tracking mode, the DDP2 loop supplies an external clock reference to a clock controller. Two DDP2 loops can operate in tracking mode, with one defined as the primary reference source for clock synchronization, the other defined as the secondary reference source. The secondary reference acts as a back-up to the primary reference.
NT5D97 Dual-port DTI2/PRI2 card 51 Reference clock errors The system software checks at intervals of 1 to 15 minutes to see if a clock controller or reference-clock error has occurred. (The interval of this check can be configured in LD 73). In tracking mode, at any one time, there is one active clock controller which is tracking on one reference clock. If a clock controller error is detected, the system switches to the back-up clock controller, without affecting which reference clock is being tracked.
ISDN Primary Rate Interface equipment overview Clock configurations Clock Controllers can be used in a single or a dual CPU system. A single CPU system has one Clock Controller card. This card can receive reference clocks from two sources referred to as the primary and secondary sources. These two sources can originate from a PRI2, DTI2, etc. PRI2 cards such as the NT8D72BA are capable of supplying two references of the same clock source.
NT5D97 Dual-port DTI2/PRI2 card 53 Table 14 Clock Controller options - description Clock Option Notes Option 1 This option provides a single CPU system with 2 clock sources derived from the 2 ports of the DDP2.

Tracking mode In tracking mode, the DDP loop supplies an external clock reference to a clock controller.
NT5D12 Dual-port DTI/PRI 71 As shown in Figure 30 "Clock Controller primary and secondary tracking" (page 71), a system with dual CPUs can have two clock controllers (CC-0 and CC-1). One clock controller acts as a back-up to the other. Lock the clock controllers to the reference clock.
ISDN Primary Rate Interface equipment overview In tracking mode, at any one time, there is one active clock controller which is tracking on one reference clock. If a clock controller error is detected, the system switches to the back-up clock controller, without affecting which reference clock is being tracked. A reference-clock error occurs when there is a problem with the clock driver or with the reference clock at the far end.
NT5D12 Dual-port DTI/PRI 73 A single CPU system has one Clock Controller card. This card can receive reference clocks from two sources referred to as the primary and secondary sources. These two sources can originate from a PRI, DTI, etc. PRI cards such as the QPC720 are capable of supplying two references of the same clock source. These are known as Ref1 (available at J1) and Ref2 (available at J2) on the QPC720. The NT5D12 card is capable of supplying two references from each clock source, i.e.

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. QPC471H and QPC775F Clock Controllers continue to be supported. Note: The NTRB53 Clock Controller cannot be combined with a QPC775 or a QPC471 card in one system The illustrations used in the description section depict a Small System.
Description 157 When only two switches are interconnected, synchronization can be achieved by operating the two systems in a master/slave mode whereby one system derives its timing from the other. However, in a network of digital systems, slips can be better prevented by forcing all digital systems to use a common reference clock (see Figure 59 "Hierarchical Synchronization" (page 159)).
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 version number of the loadware on the clock controller card will be checked against the version number stored on the system disk. If a mismatch is found and the version number in the system software database is higher, then downloading will be initiated for that card.
Description 159 In an isolated private network, the clock controller can operate in free run mode and act as a master clock to be tracked by other PBX systems in the private network. Hierarchical synchronization Figure 59 "Hierarchical Synchronization" (page 159) provides a general view of the Digital Network Clock Synchronization including the four stratum level Node Categories. Stratum 1 being the most accurate and Stratum 4 being the least accurate.
Clock Controller description and installation Stratum levels In a digital network, nodes are synchronized using a priority master/slave method. Digital nodes are ranked in Stratum levels 1 to 5. Each node is synchronized to the highest ranking node in its neighborhood with which it has a direct link. Refer to Table 62 "Node categories and stratum levels" (page 160). Table 62 Node categories and stratum levels Stratum 2 Stratum 3 Stratum 4 Accuracy +/- 1.6 * 10-8 Hz +/- 4.6 * 10-6 Hz +/- 3.
Description 161 A 1.5 Mbyte PRI contains a buffer large enough to hold about 2 full DS-1 frames (193 x 2 = 386). A 2 Mbyte PRI contains a buffer large enough to contain 2 full frames (256 x 2 = 512 bits). The buffer is normally kept half full (1 frame). Slippage has impact on the data being transferred, as is shown in Table 63 "Performance impact of one slip on service type" (page 161). All of the degradations shown in the table can be controlled or avoided with proper clock synchronization.
Clock Controller description and installation While it is beyond the scope of this discussion to provide detailed Network Synchronization, the following examples illustrate some of the basic concepts to achieve stable clocking. Figure 60 Example 1, Isolated Private Network In this example, there is no digital connection to the Central Office. Figure 61 Example 2, Isolated Private Network with Secondary Reference Clock In this example, there is no digital connection to the Central Office.
Description 163 Figure 62 Example 3, Clocking Hierarchy referenced to a Public Network Master Clock This is an example of a "STAR" arrangement— one Hub PBX is linked to the Central Office and all other PBXs are connected as slaves. When a second Digital loop from the system which forms the hub of this network becomes available, it can be used as a Secondary Clock Source in case the Primary Source fails.
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 exist (i.e. Loops X and Y). When a second Digital loop from the CO or Master M-1 becomes available, it can be used as a Secondary Clock Source in case the Primary Source fails. To avoid timing loops, in example 4-4 the most reliable slave system should not have a Secondary Clock Source (SREF= ).
Description 165 Figure 64 Example 5, digital connection to the CO In this example, digital connections to the Central Office do exist. When a second Digital loop from the CO becomes available, it can be used as a Secondary Clock Source in case the Primary Source fails. Slaves can track on each other as a secondary source since the chances of both links to the Central Offices going down at the same time are minimal. All Central Offices must have a path back to the same stratum 1 source.
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 turn be used as a clock source to other nodes. When a second Digital loop from the Master system becomes available, it can be used as a Secondary Clock Source in case the Primary Source fails.
Description 167 Figure 66 Example 7, Network Clocking with MUX In this example, the direct connection to the CO (without a MUX) should be used as a primary clock reference because this is where the least amount of hardware is involved. The MUX must pass the clock and not generate its own clock; in other words, it must be a slave (not Free Run). Synchronized clocking is required. Modes of operation There are two modes of operation, tracking mode and free run (non-tracking) mode.
Clock Controller description and installation Free run (non-tracking) mode The clock synchronization for a PRI loop can operate in free-run mode if: • the loop is not defined as the primary or secondary clock reference • the primary and secondary references are disabled • the primary and secondary references are in a local alarm state Small System Clock Controller daughterboard The Small System supports a single onboard clock controller daughterboard, the NTAK20, located on either: • the NTRB21

Installation procedures 171 Note: Switches 7 and 8 are not used. Start the Clock Controller The clock controller, when first enabled, is in free run mode. It stays in this mode for several minutes before being switched to tracking mode. Manual mode setting is possible using LD 60. All clock controllers begin tracking within approximately 15 minutes. Clock Controller commands During the installation procedure you will use some of the clock controller commands available in LD 39 and LD 60.
Clock Controller description and installation 4 Set the ENL/DIS toggle switch to DIS (disable). 5 Replacing a clock controller, do the following: • Perform a status check on the clock with the SSCK command in LD 60. The new controller should have the same status. Note: ERR20 messages can be generated. These can usually be ignored. However, excessive clock switching should be avoided, especially when counters are near the maintenance or out-of-service thresholds.
Installation procedures TRCK 14 PCK (for primary) SCLK (for secondary) FRUN (for free-run) 173 Issue the status check command, SSCK. Note: In order for the clock enhancement feature in the clock controller (NTRB53) to be fully functional, the user must issue a manual INI to activate the clock enhancement feature.
Clock Controller description and installation Note 2: ERR20 messages can be generated. These can usually be ignored. However, excessive clock switching should be avoided, especially when counters are near the maintenance or out-of-service thresholds. Excessive switching could generate threshold-exceeded messages or cause the PRI to be automatically disabled. Check the counters in LD 60. If necessary, reset the counters using the RCNT command. a. Set the old card’s faceplate ENL/DIS switch to DIS. b.
Installation procedures 175 Upgrade to an NTRB53 Clock Controller on a Single Group and Multi Group System Follow these procedures to replace the existing clock 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. Procedure 20 Remove old equipment Step Action 1 Ensure the clock controller card being removed for dual core systems is on the inactive core.

ISL installation DCHI switch settings For ISL functions, use the following switch settings for the J2 port: • RS-232 for 19.2 Kbps and below • HS (RS-422) for speeds above 19.
MSDL switch settings 181 Figure 68 NT6D11AB, NT6D11AD DCHI with ISL low-speed programming jumper settings MSDL switch settings For ISL functions, use the following switch settings. • DTE for high speed programming; • RS-232 for 19.2 Kbps and below; • External clock (in LD17) provided by modem, ADM, or ASIM, HSDM: otherwise, DCH runs at 64 Kbps. Refer to Figure 69 "MSDL/ISL settings" (page 182). Nortel Communication Server 1000 ISDN Primary Rate Interface Installation and Commissioning NN43001-301 02.
ISL installation Figure 69 MSDL/ISL settings Shared mode In shared mode, the D-channel is provided by the DCHI or MSDL card and PRI. The hardware configuration is basically the same as the ISDN PRI D-channel. See Figure 70 "ISL in shared mode" (page 183). Shared mode is established through service change in LD17, prompt USR, with the response SHA. In the shared mode, the DCH can share signaling for no more than 382 (T1) or 480 (E1) trunks, including digital and analog.
Dedicated mode using leased line 183 Figure 70 ISL in shared mode Dedicated mode using leased line In this configuration, the D-channel connects the DCHI or MSDL to a modem which communicates with a far-end modem over a dedicated leased line. See Figure 71 "ISL dedicated mode, using leased line" (page 183). A 2400 baud D-channel can support signaling for approximately 382 (T1) or 480 (E1) trunks without non-call associated messages. Both modems should be set in the synchronous mode.
ISL installation Dedicated mode using dialup modem In this configuration, the DCHI or MSDL is connected to a modem which is connected to a 500 set line card. See Figure 73 "ISL dedicated mode, using dialup Hayes Smartmodem 2400" (page 186). The call is connected to the far end through the analog (500/2500 type set) -to-TIE trunk path. To set up the D-channel, program the modem at one end in the autodial mode, so it automatically initiates a call to the other end at power up.
Dedicated mode using dialup modem 185 Table 68 "Active and stored profiles of the autodial or originating modem" (page 185) and Table 69 "Active and stored profiles of the auto answer or terminating modem" (page 185). After the software parameters have been set up, the JP1 jumpers behind the front faceplate of the Hayes Smartmodem must be dumb strapped on both modems. Next, see the Hayes Smartmodem Getting Started Guide to set up the hardware between the system and the modem.

1.5 Mb PRI implementation Figure 76 NTRB21 TMDI card faceplate NTAK09 DTI/PRI circuit card The NTAK09 Digital Trunk Interface/Primary Rate Interface (DTI/PRI) card provides the physical interface for the DS-1 facility T-1 carrier on the system. It is required for PRI and DTI operation and is also used for ISL shared-mode applications. Figure 77 "NTAK09 DTI/PRI circuit card" (page 199) shows the faceplate layout, the location of the switch and the position of the daughterboards and connectors.
Hardware description 199 Shelf slot assignments For cabinet systems, the NTAK09 DTI/PRI card can be placed in main and expansion cabinets in any single card slot given in Table 74 "Shelf slot assignments for NTRB21, NTAK09, and NTAK20" (page 202). Digital trunk cards are not supported in the Media Gateway Expansion.
1.5 Mb PRI implementation Note: Clocking slips can occur between systems that are clocked from different COs, if the COs are not synchronized. The slips can degrade voice quality. The Clock Controller circuitry synchronizes the system to an external reference clock, and generates and distributes the clock to the system. A Small System can function either as a slave to an external clock or as a clocking master.
Hardware description 201 Free-run (non-tracking) In free-run mode, the clock controller does not synchronize on any source, it provides its own internal clock to the system. This mode can be used when the system is used as a master clock source for other systems in the network. Free-run mode is undesirable if the system is intended to be a slave. It can occur, however, when both the primary and secondary clock sources are lost due to hardware faults, or when invoked by using software commands.
1.5 Mb PRI implementation Shelf slot assignments for NTRB21, NTAK09 and NTAK20 Table 74 "Shelf slot assignments for NTRB21, NTAK09, and NTAK20" (page 202) provides the shelf slot assignments for the NTRB21 TMDI card, NTAK09 DTI/PRI card, and NTAK20 Clock Controller daughterboard in Small Systems. The NTAK 93 DCH and NTBK51BA DDCH daughterboards are not included in this table since they are mounted on the NTAK09 DTI/PRI circuit card and not on a shelf.

It includes information about hardware installation and software implementation.
2.0 Mb PRI implementation Circuit card Description NTAK79 2.0 Mb PRI circuit card. Supports an onboard clock controller and an onboard D-channel handler interface. NTAK20 Clock-controller daughterboard. The system supports only one active clock controller per system or IP expansion cabinet. Note: Every cabinet or Media Gateway that contains a digital trunk must contain a clock controller. Connects to the NTBK50 PRI card. NTAK93 D-channel-handler interface (DCHI) daughterboard.
Hardware description 259 essentially replaces the D-channel circuit on the NTAK79 PRI card. (The NTAK79 PRI card does not support the NTBK51 Downloadable D-channel handler daughterboard.) A second difference between the NTAK79 and NTBK50 2.0 Mb PRI cards is that the NTAK79 has an onboard clock controller while the NTBK50 supports the NTAK20 clock controller daughterboard.
2.0 Mb PRI implementation If the NTAK93 D-channel daughterboard is attached, the NTBK50 PRI card functions in the same manner as the NTAK79 PRI card. If the NTBK51 D-channel daughterboard is attached, software is downloaded to the card instead of residing in a D-channel circuit. For information on the NTBK50 faceplate LEDs, refer to ISDN Primary Rate Interface Maintenance (NN43001-717). NTAK20 Clock Controller (CC) daughterboard The NTAK20 Clock Controller daughterboard is used with the NTBK50 2.
Install the NTAK79 PRI card 261 The DCHI is responsible for performing the Q.921 layer 2 protocol information. It transfers layer 3 signaling information between two adjacent network switches. The NTAK93 DCH daughterboard, when installed on the NTBK50 circuit card, is addressed in the same slot as the NTBK50. A minimum of one NTAK93 is required for each PRI link.

2.0 Mb ISL implementation If this a dedicated mode using dialup modems, modems such as Hayes 2400, Ventel 2400 or Gandalf 2400 can be used. In this configuration, the DCHI connects to a modem which is connected to a 500 set line card. The call connects to the far-end through the 500 set-to-TIE trunk path. Program the modem at one end in the autodial mode, so it automatically initiates a call to the other end at power up. The autodial number must be coordinated with the far-end switch.
ISL software implementation 289 Dedicated mode The DCHI uses the NTAK02 circuit card and does not support ISDN PRI signaling. The DCHI is reserved for ISL use only. The D-channel can communicate with the far-end by means of a dedicated leased line modem or dialup modem. Note that the following implementation relates to analogue TIE trunks being used as B-channels. In the case where DTI/PRI trunks are also used, then LD 17 digital loop (2.0 Mb PRI) and LD73 (2.
