Memory, Storage and CPU capacity Page 13 of 544 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. Option 11C and Option 11C Mini software is stored in various areas of the NTDK20 SSC and NTDK97 MSC cards.
PAGE 14
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
Memory, Storage and CPU capacity Page 15 of 544 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. This storage device can be an IBMtype PC or Macintosh-type computer, running an Option11C software feature called “Customer Configuration Backup and Restore” (CCBR).
PAGE 16
Page 16 of 544 Memory, Storage and CPU capacity Table 2 LD 143 CCBR commands Command Description XBK Customer database records in the Primary Flash drive are backed up to an external computer hard-drive. XRT Customer database records are restored from an external computer hard-drive to the Backup Flash drive and on the NTDK20 SSC and NTDK97 MSC. XSL The Option 11C or Option 11C Mini is remotely “sysloaded” with customer records stored in the Primary Flash drive.
PAGE 17
Memory, Storage and CPU capacity Page 17 of 544 3 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. 4 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. If the customer records are located and verified, data is loaded into DRAM.
PAGE 18
Page 18 of 544 Memory, Storage and CPU capacity Data restoring In the unlikely event configuration data becomes corrupted, a backup copy of the current database can be restored to the Option 11C and 11C Mini. There are four possible areas of where a backup of configuration data can be restored from — the secondary primary database, the backup flash drive, the PCMCIA drive, or an external computer hard-drive.

Memory, Storage and CPU capacity Page 19 of 544 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. During start-up, the Software Installation Program is automatically invoked.
PAGE 20
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. (The extension number is also predefined using the default numbering plan.
PAGE 21
Memory, Storage and CPU capacity Page 21 of 544 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). SDI ports There are three pre-programmed SDI ports on Option 11C and 11C Mini systems. The NTDK20 SSC or NTDK97 MSC provides TTY ports 0, 1, and 2.

Memory, Storage and CPU capacity Page 23 of 544 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.
PAGE 24
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.
PAGE 25
Memory, Storage and CPU capacity Page 25 of 544 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. Detailed information about the CCBR feature can be found in the Option 11C Customer Controlled Backup and Restore (CCBR) (553-3011-330).

Provisioning a new system The following summarizes the tasks required to provision a new system: 1 Define and forecast growth (page 91). 2 Estimate CCS per terminal (page 93).
PAGE 92
Page 92 of 544 Provisioning Example A customer has 180 employees and needs 100 telephones to meet the system cutover. The customer projects an annual increase of 5 percent of employees based in future business expansion. The employee growth forecast is: • 180 employees x 0.05 (percent growth) = 9 • 189 employees x 0.05 = 10 additional employees at 1 year • 199 employees x 0.05 = 10 additional employees at 2 years • 209 employees x 0.05 = 10 additional employees at 3 years • 219 employees x 0.
PAGE 93
Provisioning Page 93 of 544 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.
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
Provisioning Page 95 of 544 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. The number of lines that are accessing the group at cutover are divided into the estimated usage.
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. Table 20 lists the estimated usage on special services trunks.
PAGE 97
Provisioning Page 97 of 544 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.
PAGE 98
Page 98 of 544 Provisioning Use Reference Table 2 on page 114 to determine the quantity of trunks required to meet the trunk CCS at cutover, two-year, and five-year intervals. In this case: • 17 DID trunks are required at cutover • 18 DID trunks are required in two years • 21 DID trunk are required in five years For trunk traffic greater than 4427 CCS, allow 29.5 CCS/T.

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.
PAGE 101
Provisioning Page 101 of 544 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. • Digitone receiver holding times are 6.2 and 14.1 seconds for intra and outgoing calls respectively.
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.

Page 262 of 544 NTBK22 MISP card Functional description Each MISP can support 4 line cards (UILC or SILC or any combination of the two). Each line card supports 8 DSLs, therefore each MISP supports 32 DSLs. Since each DSL uses two B-channels and one D-channel the MISP supports 64 B-channels and 32 D-channels. If the MISP is carrying packet data, it must dedicate one of its D-channels to communicate with the external packet handler. In this case the MISP supports only 31 DSLs.

PAGE 386
Page 386 of 544 NT8D14 Universal Trunk Card Tie Two-way Dial Repeating operation In an incoming call configuration, the far end initiates a call by placing a low resistance loop across the tip and ring leads. This causes a current to flow through the battery feed resistors in the trunk circuit. Address signaling is then applied by the far end in the form of DTMF tones or dial pulses.
PAGE 387
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.

OPS service is the provision of an extension to a main subscriber loop bridged onto the loop at the serving CO or PBX. Additionally, OPS as used to denote off-premise extension service should not be confused with the OPS class-of-service assigned in the Single-line Telephone Administration program (LD10).

This plan determines the port-to-port loss for each call. When a port is configured for OPS class-ofservice, loss is programmed into the OPS analog line card on a call-by-call basis.
PAGE 436
Page 436 of 544 NT1R20 Off Premise Station (OPS) analog line card The overall range achievable on an OPS line facility is limited by the signaling range (2300 ohm loop including telephone set resistance). Signaling range is unaffected by gain treatment; thus, gain treatment can be used to extend the voice range to the limit of the signaling range. For example, on 26 AWG wire, the signaling range of 2300 ohms corresponds to an untreated metallic loop loss of 15 dB. Gain treatment (such as a VFR) with 10.

For example, wireless portables loudness characteristics are selected for connections to switching systems for wireless communication systems; if deployed in an OPS arrangement without due consideration for these characteristics, the result could be a significant deviation from optimum loudness performance.
