System architecture Hardware architecture CS 1000M and Meridian 1systems are circuit-switched digital systems that provide voice and data transmission. The internal hardware is divided into the following functional areas (see Figure 13 "Large System basic architecture" (page 35) on Figure 13 "Large System basic architecture" (page 35)): • Common Control Complex (Common Equipment) circuit cards provide the processor control, software execution, and memory functions of the system.
Hardware architecture 35 Figure 13 Large System basic architecture Common control complex The processor is the common control complex of the system. It provides the sequences to process voice and data connections, monitor call activity, and perform system administration and maintenance. The processor communicates with the network interface over a common control bus that carries the flow of information.
System architecture • the disk drive unit that provides mass storage for operating programs and data • I/O interfaces that provide an information exchange between the user and the system CS 1000M and Meridian 1"core" processor cards support extensive networking and provide intensive use of software features and applications, including call centers of up to 1000 agents.
Hardware architecture 37 In the CS 1000M SGand Meridian 1 PBX 61C CP PIVCore/Network module, the core side houses the following equipment: • • • • • one Call Processor Pentium IV® (CP PIV) card one System Utility (Sys Util) card one Core-to-Network Interface (cCNI) cards one System Utility Transition (Sys Util Trans) card four cCNI Transition (cCNI Trans) cards Cabling between the CP cards allows memory shadowing and dual-CPU operation.
System architecture Core/Net modules diagnose faults in field-replaceable units for all core hardware, including cables. In case of a failure, a message appears on the system terminal and on the LCD of the faceplate of the utility card. Core to Core Ethernet connection (LAN1 to LAN2) between the CP PIV cards allows memory shadowing and dual-CPU operation. The cCNI Transition cards connect the Core module cards to the 3PE cards in the Network modules.
Hardware architecture 39 The System Utility card supports Card ID. The card provides an interface between the security device and the computer, and an interface between the XSM and display panel for each Core/Net card cage. This card also includes a switch on the faceplate to enable or disable the Core cards. The System Utility Transition card provides connections for the security device, the system monitor, and the status panel.
System architecture Network organization Network loops are organized into groups. A system is generally configured as one of the following: • • • a half group system (CS 1000M HG) that provides up to 16 loops a single group system (CS 1000M SG) that provides up to 32 loops a multi-group system (CS 1000M MG) that provides up to 256 loops The Fiber Junctor Interface (FIJI) cards in the Network modules are connected with fiber-optic cables to form a Dual Ring Fiber Network.
Hardware architecture 41 Superloop network configurations By combining four network loops, the superloop network card makes 120 timeslots available to IPE cards. Compared to regular network loops, the increased bandwidth and a larger pool of timeslots increases network traffic capacity for each 120-timeslot bundle by 25 percent (at a P0.1 grade of service). The NT8D37 IPE module is divided into segments numbered 0–3 of four card slots each (see Figure 15 "Superloop segments in the IPE module" (page 41)).
System architecture • four segments per superloop requires one superloop network card and one controller-2 card • eight segments per superloop requires one superloop network card and two controller-2 cards • one segment per superloop/three segments on a second superloop requires two superloop network cards and one controller-2 card • two segments per superloop/six segments on a second superloop requires two superloop network cards and two controller-2 cards As an example of a superloop configura
Hardware architecture 43 Figure 16 Eight segments per superloop Intelligent Peripheral Equipment Using pulse code modulation (PCM), Intelligent Peripheral Equipment (IPE) converts analog signals to digital signals before switching is performed by the network. This conversion method samples the amplitude of the analog signal at a rate of twice the highest signal frequency, then converts the amplitude into a series of coded pulses. For telecommunications, the PCM-sampling frequency standard is 8 kHz.
System architecture IPE is associated with network loops. IPE cards are supported by NT8D04 Superloop Network Card loops. The traffic requirements of all IPE cards provisioned on a particular network loop must match the traffic capacity of that loop.

System architecture Any medium that conforms to the DS-1 format (1.544 Mbps) can be used to link local and remote sites, including digital microwave radio and fiber-optic transmission systems. Terminal equipment Large Systems support a wide range of telephones, including multiple-line and single-line telephones, as well as digital telephones with key and display functions and data transmission capabilities.
Hardware architecture 47 Meridian attendant consoles support attendant message center options. The attendant console can be connected to a PC to provide electronic directory, dial-by-name, and text messaging functions. All call processing features can be accessed using the computer keyboard. Power equipment Large Systems provide a modular power distribution architecture.
System architecture power" (page 48)). An AC-powered system that does not require long-term backup can benefit from a UPS with short-term backup because the UPS typically provides power conditioning during normal operation, as well as reserve power during short outages or blowouts.
Hardware architecture 49 Figure 18 ExternalDC-power architecture with reserve power Candeo DC power system The Candeo platform provides a simple, quick-to-deploy, and easy-to-operate power solution. Based upon modular building blocks (rectifiers, System Manager, DC distribution, and battery connection modules), the system is designed to power -48 V DC applications.
System architecture CS 1000 Release 5.5 introduces three new servers that can host a CS 1000 Release 5.5 Signaling Server: • • • “Nortel Common Processor Pentium Mobile server” (page 50) “International Business Machines X306m server” (page 51) “Hewlett Packard DL320-G4 server” (page 51) The Signaling Server has both an ELAN and TLAN network interface. The Signaling Server communicates with the Call Server through an ELAN subnet. The Signaling Server is mounted in a 19-inch rack.
Hardware architecture 51 The Nortel CP PM server has the following components: • • • • • • • • Intel Pentium M processor (1.4 Ghz) internal hard drive hot-pluggable Compact Flash (CF) card slot in the faceplate 2 GB of SDRAM One 1 GB/s Ethernet port Two 100BaseT Ethernet ports Two serial ports One USB port For more information about installing and configuring the Nortel CP PM server as a Signaling Server, seeSignaling Server Installation and Commissioning (NN43001-312), .
System architecture The HP DL320-G4 1U server has the following components: • • • • • • • • Intel Pentium 4 processor (3.6 GHz) Two 80 GB SATA Hard drives (1 configured) 4 GB PC2-4200 ECC DDR2 SDRAM (2 GB configured Two 10/100/1000BaseT Ethernet ports One CD-R/DVD ROM drive One serial port Three USB ports For more information about installing and configuring the HP DL320-G4 server as a Signaling Server, see Signaling Server Installation and Commissioning (NN43001-312), .
Hardware architecture 53 Network Routing Service NRS for CS 1000 Release 5.5 software is offered in two versions: a SIP Redirect Server NRS and a SIP Proxy NRS. The SIP Redirect Server NRS is hosted either co-resident with Signaling Server applications, or in a stand-alone mode on a dedicated Common Processor Pentium Mobile (CP PM) server running the VxWorks™ real-time operating system. There are no changes to the SIP Redirect Server NRS in CS 1000 Release 5.5.
System architecture The H.323 Gatekeeper and the SIP Redirect Server can reside on the same Signaling Server. Examples of H.323 and SIP-compatible endpoints needing the services of the NRS are CS 1000E. The NRS also supports endpoints that do not support H.323 Registration, Admission, and Status (RAS) or SIP registration with the NRS. Note: Systems that do not support H.323 RAS procedures and H.323 Gatekeeper procedures are referred to as non-RAS or static endpoints.
Software architecture 55 Element Manager Element Manager is a software application that provides a web interface to support administration of system components, including the Signaling Server. With Element Manager, single web pages provide access to information traditionally spread throughout multiple overlays.
System architecture Call processing, maintenance, and administration are controlled by software programs stored either as firmware programs, as software programs resident in system memory, or as nonresident programs on disk. The information that describes system configuration and associated IPE is called office data. This data resides in the system memory and on disk.
Software architecture 57 All software programs, including the nonresident programs listed in the following section are resident in, and accessible from, the memory on the cards listed above. Nonresident programs Nonresident programs are stored on data disks and loaded into the overlay area of system memory to perform specific tasks. They are removed from the overlay area when no longer required.
System architecture Traffic All systems are equipped with traffic data accumulation programs. There is also a resident traffic print program that examines the schedules, transfers data from accumulating to holding registers in accordance with schedules, and prints the traffic data. In addition, there is a traffic program used to query and modify schedules, options, and thresholds. Equipment data dump After making service changes, the changes must be saved to disk in order to save them.
Configuration options 59 In a distributed system, subscriber connections are the same at local IPE modules as they are at Remote IPE modules or small cabinets. Furthermore, because Remote IPE equipment uses common and network equipment from the local system, subscriber functions and features are the same at local and remote sites. Figure 19 "Large System to Remote IPE site" (page 59) illustrates the fiber-optic connection between a local system and remote system.
System architecture The Fiber Remote Multi-IPE Interface links the local and remote systems using a fiber-optic link over a single-mode optical fiber.
Configuration options 61 Carrier Remote IPE The Carrier Remote IPE provides functionality by installing only IPE modules and IPE cards at a distant site. The Remote IPE shares the system’s Common and Network Equipment to provide the same functions and features to remote subscribers that are available to local system subscribers. A floor-standing column or a wall-mounted cabinet Carrier Remote IPE is installed at the remote site and is connected to the Meridian 1 Large System using T1 or E1 connection.
System architecture Branch Office The Branch Office feature extends system features from a main office to one or more branch offices. A branch office is an MG 1000B Core connected to an IP PBX at the main office over an enterprise IP network or over a WAN. This configuration enables a secondary location to centralize the call processing of its IP-based communications network. The Call Server at the main office provides the call processing for the IP Phones in both the main office and branch offices.
