Page 15: Description
H.323 IP Telecommuter clients, and the telephone sets and trunks behind the Meridian 1 in the enterprise network are supported. In addition, a subset of the Meridian 1 set features, such as Conference, Transfer, Hold and Message Waiting Notification are available to the H.323 IP clients, much like a regular digital set behind the Meridian 1.
Page 16: Ip Line Card Gateways
IP Line card Gateways Gateways in the system contain two interfaces: one interface to the Meridian 1, and the other is an H.323 interface to the IP network. The Gateway provides the necessary conversion for both call signaling and voice stream/packets across the two interfaces. IP Line cards provide the Gateway functionality.

Page 28: Ip Line Card Functional Description
Page 28 of 262 Description IP Line card functional description Card Roles The three major card roles are: • active leader: performs IP address assignment, interfaces with MAT, and performs Gatekeeper and Gateway functions. • backup leader: acts as a Gateway that monitors the heartbeat of active leader, and will take over the active leader functions if the active leader fails.
Page 29 These address translation databases are then used by the Gatekeeper to perform address translation whenever a call is made from the Meridian 1 to an IP client, from an IP client to the Meridian 1, or from an IP client to an IP client.
Page 30 Page 30 of 262 Description The value of Time To Live that is specified for the Gatekeeper provides the duration of the Registration. Admission Admission occurs when a client or Gateway attempts to make a call. The Gatekeeper authenticates the Clients and Gateways involved. Admission occurs between both the originating and terminating sides and the Gatekeeper per H.323.
Page 31: Ip Address Distribution
Description Page 31 of 262 Gatekeeper Fallover Both the active leader and backup leader run the Gatekeeper software. When the backup leader takes over for the active leader upon failure of the active leader heartbeat, the Gatekeeper on the backup leader takes over for the Gatekeeper on the active leader.

1HWZRUN#HQJLQHHULQJ#RYHUYLHZ Traditionally Meridian 1 networks rely on voice services such as LEC and IXC private lines. With ITG technology, the Meridian 1 can now choose a new kind of delivery mechanism, one that uses packet-switching over a data network, specifically a corporate intranet. The role of the IP Line Card in this regard is essentially to convert steady data stream digital voice into fixed-length IP packets, and vice versa.

IP Telecommuter Engineering Guidelines Page 53 of 262 6HWWLQJ#XS#D#V\VWHP#ZLWK#VHSDUDWH#VXEQHWV#IRU#YRLFH #DQG#PDQDJHPHQW It is highly recommended that the customer place the voice and management LANs on separate dedicated subnets, separated by a router. The ITG cards have two Ethernet ports per card, so the ITG system can support two different networks for the voice interface (Telephony LAN or T-LAN) and management interface (Embedded LAN, or E-LAN) connections.
Page 54: Single Subnet Option For Voice And Management
IP network is most likely at a Remote Access Server/Router or the router directly connected to the T-LAN of Meridian 1 ITG. The impact of the call will be calculated for the T-LAN only. We will assume that it does not use the intranet of an enterprise (if it has one).
Page 55 IP Telecommuter Engineering Guidelines Page 55 of 262 To calculate the bandwidth requirements of a route, the total route traffic after having been divided by 36, should be multiplied by the bandwidth usage per port to obtain the data rate requirement of that route.

IPE shelf of 16 slots. Therefore, a maximum of 8 ITG Line Cards per shelf are allowed. The ITG Line Card will appear to the Meridian 1 as an XDLC Line Card. Each port is associated with one H.323 Client, hence an ITG Line Card can support 24 registered H.323 Clients.
Page 57 IP Telecommuter Engineering Guidelines Page 57 of 262 Due to the capacity limitation of an ITG Line Card processor, a card can process 15 simultaneous calls with minimum packet delay or loss. To protect QoS of calls in progress, when the 16th call comes in, it will be blocked and not allowed into the system under the flow control rule implemented in the ITG software.

Page 62: Decision: Sufficient Capacity
Page 62 of 262 IP Telecommuter Engineering Guidelines Suppose the intranet has a topology as shown in Figure 18, and the technician wants to predict the amount of traffic between the IP Telecommuter node and corporate intranet. From the IP Telecommuter Traffic Engineering section and traceroute measurements, traffic between IP Telecommuter node and subnet A, IP Telecommuter node and subnet B, and IP Telecommuter node and Router/Server C are collected.
Page 63: Insufficient Link Capacity
IP Telecommuter Engineering Guidelines Page 63 of 262 Some network management systems have network planning modules that compute network flows in the manner just described. These modules provide more detailed and accurate analysis as they can take into account actual node, link and routing information.

Page 69 IP Telecommuter Engineering Guidelines Page 69 of 262 /DWH#SDFNHWV Packets that arrived outside of the window allowed by the jitter buffer are discarded by the ITG. To determine which ping samples to ignore, first calculate the average one-way delay based on all the samples. Then add 500 ms to that.
Page 70 Page 70 of 262 IP Telecommuter Engineering Guidelines In order to offer good voice quality, the technician should keep the network σ operating region within a “Good” or “Excellent” QoS level. Mean If the expected QoS levels of some or all routes fall short of being “Good”, the technician will need to evaluate the options and costs for upgrading the intranet.
Page 71 IP Telecommuter Engineering Guidelines Page 71 of 262 1HWZRUN#)LQH0WXQLQJ There are a number adjustments can be made to fine-tune the network and to improve its QoS. Here are some practical approaches. 5HGXFLQJ#GHOD\V In this and the next few sections, the guidelines explore different ways of cutting down one-way delay and packet loss in the IP telephony network.
Page 72 5HGXFLQJ#KRS#FRXQW The IP Line card nodes must be connected to the intranet so as to minimize the number of router hops between the Meridian 1 systems, assuming adequate bandwidth on the WAN links for the shorter route. This will reduce the fixed and variable IP packet delay, and improve the Voice over IP Quality of Service.
Page 73 IP Telecommuter Engineering Guidelines Page 73 of 262 5HGXFLQJ#SDFNHW#HUURUV Packet errors in intranets are generally correlated with congestion somewhere in the network. Bottleneck links tend to be where the packet errors are high because packets get dropped when they arrive faster than the link can transmit them.
Page 74 Page 74 of 262 IP Telecommuter Engineering Guidelines $GMXVWLQJ#MLWWHU#EXIIHU#VL]H The jitter buffer parameters directly affect the end-to-end delay. Lowering the voice playout settings decreases one-way delay, but this comes at the expense of giving less waiting time for voice packets that arrive late. The jitter buffer size is adjustable through the MAT input.
Page 75 IP Telecommuter Engineering Guidelines Page 75 of 262 When an intranet takes on a real-time service, the users of that service will impose additional QoS objectives in the intranet; some of these targets may be less stringent compared with those imposed by current services, while other targets would be more stringent.
Page 76 Page 76 of 262 IP Telecommuter Engineering Guidelines In most corporate environments, the intranet primarily supports data and other services. When planning to offer voice services over the intranet the technician needs to assess the following: • Are there existing QoS mechanisms? What kind? The IP Telecommuter traffic should take advantage of established mechanisms if possible.
Page 77 It is assumed that the customer’s organization already has processes to monitor, analyze, and re-design both the Meridian 1 network and the corporate intranet so that both networks continue to conform to internal quality of service standards.

Timer and DMA tests • DSP test FPGA testing Prior to communication with the Meridian 1, the 8051XA controller will download FPGA data files and perform tests to ensure correct programming of the FPGA. Troubleshooting a software load failure Symptoms MAT cannot establish connection with IP Line card.
Page 242 Page 242 of 262 Maintenance Three known reasons can cause the failure to load the ITG software: • Not enough memory due to a faulty or missing SIMM. • Corruption of the ITG software image in flash memory. • The escape sequence to boot from the BIOS has been inadvertently sent down the serial line due to noise.
