System architecture Contents This section contains information on the following topics: "Hardware architecture" (page 36) "Common control complex" (page 37) "Network interface" (page 41) "Intelligent Peripheral Equipment" (page 44) "Terminal equipment" (page 47) "Power equipment" (page 48) "Signaling Server" (page 50) "Software architecture" (page 56) "Firmware" (page 56) "Software" (page 56) "Office data" (page 57) "Resident programs" (page 57) "Nonresident programs" (page 57) "Configuration options" (
System architecture Hardware architecture CS 1000M and Meridian 1 systems 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 37) on Figure 13 "Large System basic architecture" (page 37)): • Common Control Complex (Common Equipment) circuit cards provide the processor control, software execution, and memory functions of the system.
Hardware architecture 37 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 • one Core-to-Network Interface (cCNI) cards • one System Utility Transition (Sys Util Trans) card • four cCNI Transition (cCNI Trans) cards 39 Cabling between the CP cards allows memory shadowing and dual-CPU operation. The CNI and CNI-3 cards provide the interface between the IPB and the network shelf, and between the CP card and three-port extender cards in the network shelf. Each CNI card provides two ports. Each CNI-3 card supports three ports.
System architecture The cCNI Transition cards connect the Core module cards to the 3PE cards in the Network modules. Each Core module contains between one and four cCNI cards. Since each cCNI card can connect up to two Network groups, each Core is connected to a minimum of two groups and a maximum of eight groups. The number of cCNI cards in a system depends on the number of Network groups in that system.
Hardware architecture 41 The cCNI Transition cards provide the cable connections to the 3PE Termination Panel at the back of the module. A cCNI Transition card is mounted directly behind each cCNI card (on the back of the Core backplane). Four cCNI Transition cards for Core/Net module are installed in the factory regardless of how many cCNI main cards are configured for the system. Network interface Network switching, based on digital multiplexed loops, interconnects peripheral ports.
System architecture The Dual Ring fiber-optic cable configuration provides complete non-blocking communication between the Network groups; this eliminates the incidence of busy signals for calls switched between groups. Each FIJI card can handle 32 PCM links. A system of eight Network groups provides 8000 timeslots for 4000 simultaneous conversations. This Dual Ring network is fully redundant: each of the fiber-optic cable rings is capable of handling the traffic for an entire eight group network.
Hardware architecture 43 Figure 15 Superloop segments in the IPE module A superloop is made up of NT8D04 Superloop Network cards, NT8D01AC or NT8D01BC Controller-4 or NT8D01AD Controller-2 cards, and from one to eight IPE segments. The NT8D01BC Controller-4 replaces the NT8D01AC and NT8D01AD Controller cards for replacements and new installations.
System architecture As an example of a superloop configuration, Figure 16 "Eight segments per superloop" (page 44) shows eight segments per superloop. If a segment in this configuration is equipped with analog line cards and trunk cards, a high concentration environment of 120 timeslots to 128–512 Terminal Numbers (TNs) is provided. If half of the data TNs on digital line cards are enabled, this configuration provides a concentration of 120 timeslots to 768 TNs.
Hardware architecture 45 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. Compressing-expanding (companding) PCM is a standard technique for using 8-bit words to efficiently represent the range of voice and data signals. Two standards for companding, A-Law and µ-Law, are recognized worldwide.

Hardware architecture 47 Intelligent Peripheral Equipment remote location In a local operating environment, IPE can be housed up to 15.2 m (50 ft) from the Common Equipment. IPE installed in a remote location extends this range, allowing approximately 112.6 km (70 miles) between local and remote facilities. This extension is achieved by converting multiplexed loop signals to a form compatible with the commonly used T-1 type digital transmission system.
System architecture Attendant consoles Meridian 1 attendant consoles provide high-volume call processing. Indicators and a 4 x 40 liquid crystal display (LCD) provide information required for processing calls and personalizing call answering. Loop keys and Incoming Call Indicator (ICI) keys allow the attendant to handle calls in sequence or to prioritize answering for specific trunk groups. An optional busy lamp field provides the attendant with user status.
Hardware architecture 49 AC power AC-powered systems require no external power components and can plug directly into commercial AC (utility) power. AC-powered systems are especially suitable for applications that do not require reserve power. They are also recommended systems that require reserve power with backup times ranging from 15 minutes to 8 hours.
System architecture A variety of rectifiers and distribution equipment can be used to supply external DC power. Existing customer equipment can be used or a system that Nortel either supplies or recommends, such as the Small or Large Candeo, can be used. The Small Candeo is appropriate for Single Group or Multi Group systems that do not require more than 300 A, while the Large Candeo is suitable for larger systems.
Hardware architecture 51 The legacy Nortel ISP1100 Signalling Server can still be used. CS 1000 Release 5.0 introduces three new servers that can host a CS 1000 Release 5.0 Signaling Server: • "Nortel Common Processor Pentium Mobile server" (page 51) • "International Business Machines X306m server" (page 52) • "Hewlett Packard DL320-G4 server" (page 52) The Signaling Server has both an ELAN and TLAN network interface. The Signaling Server communicates with the Call Server through an ELAN subnet.
System architecture 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).
Hardware architecture 53 • 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). Terminal Proxy Server The Terminal Proxy Server (TPS) acts as a signaling gateway between the IP Phones and the Call Server using the UNIStim protocol.
System architecture 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 5.0. The SIP Proxy NRS is hosted in a stand-alone mode on a dedicated commercial off the shelf server running the Linux™ real-time operating system.
Hardware architecture 55 SIP Proxy Communication Server (CS) 1000 Release 5.0 adds a transaction stateful SIP Proxy to the IP Peer Network. A SIP Proxy acts as both a server and a client. A SIP Proxy receives requests, determines where to send the requests, and acting as a client on behalf of SIP endpoints, passes requests to another server. A SIP Proxy makes the following features and functionality, which are provided by CS 1000 Release 5.0, possible: 1. Transport Layer Security (TLS).
System architecture NRS Manager NRS Manager is a web-based management application used to configure, provision, and maintain the NRS.
Software architecture 57 Office data Office data describes the characteristics of the system in terms of configuration and call-dependent information, such as features and services. Office data is arranged in blocks defining IPE, system configuration, and transient data. Resident programs Resident programs are always available in memory during system operation. Some resident programs are permanently programmed into the ROM portion of system memory.
System architecture Software programs provide the system interface for maintenance, service change, and traffic measurement. Each program is independent and has its own specific set of commands and formats. These programs run concurrently with normal call processing without interfering with system traffic.
Configuration options 59 The data dump program is also used to install a new generic version or issue and capture protected data store information (such as speed call lists) that may be changed by a user. Software audit This program monitors system operation and gives an indication of the general state of the system operation. The program is concerned mainly with the system software. When a software problem is encountered, the program attempts to clear the problem automatically.
System architecture Figure 19 Large System to Remote IPE site Fiber Remote Multi-IPE Interface The Fiber Remote Multi-IPE Interface links a Large System with one or more Remote IPE sites to provide Meridian 1 Large System functionality. Since the remote IPE system uses the Common Equipment and Network Equipment of the associated local Large System, it can deliver the same features and functionality as the local system.
Configuration options • Multi-mode fiber supporting four superloops • Multi-mode fiber supporting two superloops 61 Figure 20 Meridian 1 Large System to Remote IPE connection over fiber-optic link For more information on Fiber Remote IPE, seeFiber Remote IPE Fundamentals (NN43021-554). For more information on the Fiber Remote Multi-IPE Interface, see Fiber Remote Multi-IPE Interface Fundamentals (N43021-556).
System architecture 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. Figure 21 "Meridian 1 Large System to Carrier Remote IPE links" (page 62) illustrates the connection between the local system and remote system. Figure 21 Meridian 1 Large System to Carrier Remote IPE links For more information on Carrier Remote IPE, see Carrier Remote IPE Fundamentals (NN43021-555).
Configuration options 63 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. The MG 1000B Core provides call processing functionality to local digital telephones and analog devices. The MG 1000B Core also provides digital and analog trunk access to the local Public Switched Telephone Network (PSTN).
