    Memory, Storage and CPU capacity An Option 11C with IP Expansion can be made up of both Option 11C cabinets and Option 11C Mini chassis. However, when an Option 11C Mini chassis is used, the NTDK97 Mini System Controller (MSC) card is replaced with an NTDK20 Small System Controller (SSC) card and an appropriate IP Expansion daughterboard.

    Page 14 of 544 Memory, Storage and CPU capacity Data storage The Option 11C and 11C Mini data dump performed in LD 43, is the system’s method of backing up configuration data to its file storage devices. By invoking one of the several data dump commands in the overlay, the user is ensured that at least one backup copy of configuration data exists in a location other than DRAM (Refer to Table 1).

  • Page 15

    Figure 1 Data storage on the NTDK20 SSC and NTDK97 MSC The Option 11C and Option 11C Mini offer one additional area of data storage that is truly external to the switch.

    If the customer records cannot be located in the Backup Flash drive, the Option 11C and 11C Mini automatically searches the PCMCIA drive. If customer records are located and verified, data is loaded into DRAM. If the customer records cannot be located in the PCMCIA drive, the Option 11C and 11C Mini searches the Primary Flash drive for the secondary backup (.bak) file.

    service. This can be a significant time-saver if you have to program numerous types of telephone models. Pre-programmed data is not mandatory for software installation. In fact, the NTDK20 or the NTDK97, can be programmed with the minimum number of files to allow the Option 11C and 11C Mini to operate.

    Page 20 of 544 Memory, Storage and CPU capacity Telephone models simplify telephone installation. During telephone activation, the telephone prompts you to accept a default model. If a model is chosen, all keys are automatically assigned a feature and no further key programming is required.

    If the default numbering plan does not suit this system’s needs, you can change it using the procedures Chapter 22 of the Option 11C Planning and Installation (553-3021-210) or Appendix A of the Option 11C Mini Planning and Installation (553-3021-209).

    Removing pre-programmed data Pre-programmed data cannot be removed from the Option 11C or Option 11C Mini system once it is loaded into the system. However, pre-programmed data can be bypassed during first-time system installations. During start-up, the Software Installation Program is automatically invoked. The Option 11C and 11C Mini then loads system data from the Software Daughterboard, or MSC for the Option 11C Mini, and prompts the user for a variety of information, including the time and date, type of installation,...

    Page 24 of 544 Memory, Storage and CPU capacity The second function of the CCBR feature has to do with the role it plays in upgrading software from an Option 11 or 11E to an Option 11C system. To illustrate, if the CCBR feature is invoked in LD 43 of an Option 11 or 11E, its configuration data can be backed up on a hard-drive of an external computer.

    Remote access Remote access to the Option 11C or Option 11C Mini is established by connecting SDI port 0, 1, or 2 on the SSC/MSC to an analog line (Central Office line) through an on-site modem. This will allow the computer to dial directly into the Option 11C or Option 11C Mini from a remote location.

Network Delay There is some impact on real-time performance (estimated to be 20%) when digital trunks are installed in IP Expansion cabinets. However, there is still sufficient real-time to support five fully configured Option 11C cabinets in a typical business configuration.

    Estimating CCS per terminal Estimate the station and trunk CCS per terminal (CCS/T) for the installation of a system using any one of the following methods: • comparative method • manual calculation • default method Comparative method Select three existing systems which have a record of traffic study data. The criteria for choosing comparative systems are: •...

  • Page 94

    Page 94 of 544 Provisioning If only the trunk CCS/T is available, multiply the trunk CCS/T by 0.5 to determine the intra-CCS/T (assuming a normal traffic pattern of 33 percent incoming calls, 33 percent outgoing calls, and 33 percent intra-system calls). The trunk CCS/T and intra CCS/T are then added to arrive at the line CCS/T (see the example in Table 18).

  • Page 95

    Manual calculation Normally, the customer can estimate the number of trunks required at cutover and specify the grade of service to be maintained at two-year and five-year periods (see Table 19). (If not, use the comparative method described on page 93.) The number of trunks can be read from the appropriate trunking table to select the estimated usage on the trunk group.

  • Page 96

    Page 96 of 544 Provisioning This method is used for each trunk group in the system, with the exception of small special services trunk groups (such as tie, WATS, and FX trunks). Normally, the customer will tolerate a lesser grade of service on these trunk groups.

  • Page 97

    Example: • 275 stations at cutover • 304 stations at two years • 352 stations at five years Cutover: 275 x 5.5 (CCS/T) x 2 = 3025 CCS total system load Two-year: 304 x 5.5 (CCS/T) x 2 = 3344 CCS total system load Five-year: 352 x 5.5 (CCS/T) x 2 = 3872 CCS total system load Table 21 Default method and manual calculations analysis...

    Calculating Digitone receiver requirements The NTDK20 SSC card and the NTDK97 MSC card meet all DTR requirements. DTR provisioning methods are provided below for exceptional cases requiring extra DTR capacity. The Option 11C system has 50 universal card slots when four expansion cabinets are equipped.

  • Page 100

    Page 100 of 544 Provisioning Model 1 Table 24, “Digitone receiver (DTR) requirements — Model 1,” on page 117 is based on the following factors: • 33 percent intra-office calls, 33 percent incoming calls, and 33 percent outgoing calls • 1.5 percent dial tone delay grade of service •...

  • Page 101

    Detailed calculation: Method 1 This method can be used when there are no incoming Digitone DID trunks and the following is assumed: • Digitone receiver traffic is inflated by 30 percent to cover unsuccessful dialing attempts. • Call holding time used in intra-office and outgoing call calculations is 135 seconds if unknown.

  • Page 102

    Page 102 of 544 Provisioning Detailed calculation: Method 2 This method is used when incoming Digitone trunks are included in the system. This method uses the same assumptions as Method 1, with the DTR holding time assumed to be 2.5 seconds for a DID call. Follow the procedure below for detailed calculation Method 2.

    NT8D14 Universal Trunk Card Page 387 of 544 Paging operation In the Paging mode, the Universal Trunk is connected to a customer-provided paging amplifier system. When the trunk is accessed by dial-up or attendant key operation, it provides a loop closure across control leads A and B. In a typical application, this will transfer the input of the paging amplifier system to the transmission path of the trunk.

    Tracking mode There are two stages to clock controller tracking: • tracking a reference • locking on to a reference. When tracking a reference, the clock controller uses an algorithm to match its frequency to the frequency of the incoming clock. When the frequencies are very near to being matched, the clock controller is locked on to the reference.

    External timing interface The clock controller provides an external timing interface and can accept two signals as timing references. An external reference is an auxiliary timing clock which is bridged from a traffic carrying signal and is not intended to be a dedicated non-traffic-bearing timing signal.
