Page 59: Port Management
Remote Office 9150 description Call on demand versus permanent connections The ISDN connection between the MIG RLC and Remote Office 9150 unit can be a permanent or call on demand connection. The connection type is defined on the MIG RLC port to which the Remote Office 9150 unit is assigned.
Page 60 For more details, see “Station priority” on page 52. Local calling The Remote Office 9150 unit allows you to place calls to other extensions within your office, or to telephones in your local community. This is accomplished through the use of up to two local call appearance keys.
Page 61 PSTN line. If you make an emergency service call from a station that is connected to the Remote Office 9150 unit, the call is routed through the host PBX, which could be in a different city.
Page 62: System Security
Introduction This section describes the security levels that are supported for controlling access from the Remote Office 9150 unit to the MIG RLC on the host PBX. No security When no security measures are used, the MIG RLC accepts all incoming calls from the Remote Office 9150 site.
Page 63 MIG RLC port to which the Remote Office 9150 unit is assigned. If the identifiers match, access is granted. If the identifiers do not match, an event is recorded in the Remote Office 9150 unit system log, which can be viewed in Configuration Manager. The telephone that was used to make the call displays a message indicating that communications with the host PBX are down.
Page 64: Trunking, Connection Types, And Call Timers
Connection types The Remote Office 9150 connection to the MIG RLC can be defined on the MIG RLC as a permanent or demand connection. A permanent connection means that the ISDN connection to the host PBX always remains open. A demand connection means that the ISDN connection opens only when a connection with the host PBX is required.
Page 65 March 2000 Remote Office 9150 description Minimum call duration timer Most ISDN tariffs specify a minimum length of time for which you are charged when you open the line, regardless of the call duration. This is the same as the minimum call charges listed on long distance telephone bills.
Page 66 Remote Office 9150 description Standard 1.0 Example 2 If the call lasts for 65 seconds and no other calls are made, the ISDN connection drops after another 60 seconds has passed without activity. Since the ISDN call exceeded 59 seconds, the minimum call duration timer no longer applies. The idle timer is used, in this case, to prevent further ISDN charges.

Page 75 Remote Office 9150 description Offline IP network measurements Once the Remote Office 9150 unit has reverted to using its PSTN connections, it must continually monitor the IP network to determine an appropriate time to restore voice traffic to the IP network as follows: Pseudo voice traffic is placed on the IP network by both the MIG RLC and the Remote Office 9150 unit.
Page 76: Port Management
Remote Office 9150 description Standard 1.0 Port management Introduction You can assign Remote Office 9150 stations to one of the following types of MIG RLC ports: single-user ports multi-user voice ports dynamic port pool Port types are assigned on the MIG RLC. Refer to the Meridian Internet Gateway Reach Line Card Installation and Administration Guide (NTP 555-8421-210) for detailed instructions.
Page 77 March 2000 Remote Office 9150 description Dynamic port pool Dynamic port pooling is similar to a multi-user port except that the persons who share ports in a dynamic pool are assigned to the next available port in the MIG RLC port pool. There is no correlation between the station and the port on the MIG RLC.
Page 78: Station Priority
Calls transition between the IP and circuit-switched networks whenever voice QoS levels change. (The voice QoS levels are defined on the Quality of Service screen on the MIG RLC for your Remote Office 9150 unit.)
Page 79 March 2000 Remote Office 9150 description The number of stations that can be configured as high priority depends on the amount of available bandwidth.

Page 249: Subnet Mask
March 2000 Configuring the Remote Office 9150 unit Subnet mask A network can be broken down into one or more physical networks, each of which forms a subset of the main network. This process is called subnetting, or creating a subnet.
Page 250 Configuring the Remote Office 9150 unit Standard 1.0 Remote site 1 Router Headquarters Router Router Remote Remote site 2 site 3 G101483 Subnets offer a solution to this problem. In the illustration on the next page, each branch is on network 92 and has a unique subnet. Generally, traffic does not leave its subnet unless the traffic’s destination is on a different subnet.
Page 251 G101419 In this case, the subnet mask is 255.255.0.0. When it is configured on the Remote Office 9150 unit, this tells the Remote Office 9150 unit that the first 16 bits of the IP address represent the network and subnetwork.
Page 252: Default Gateway
A gateway is a device that functions as a node on two or more networks, forwarding packets from one network to addresses in the other networks. In a Remote Office 9150 context, the gateway is the device on the network that directs traffic to and from the Remote Office 9150 unit.

March 2000 Network engineering guidelines Remote Office traffic engineering Introduction To design a network, you must size it so that it can accept some calculated amount of traffic. The purpose of the Remote Office network is to deliver voice traffic meeting the QoS objectives. Since traffic determines network design, the design process needs to start with determining a Remote Office traffic forecast.

Page 405 March 2000 Network engineering guidelines Adjust requirement for traffic peaking Peak hour bandwidth per node = Bt*1.3 (default) A peak factor of 1.3 is the default value used to account for traffic fluctuation in the busy hour due to non-queued, Poisson random distribution of call originations.
Page 406 Peak hour bandwidth requirement = 722*1.3 = 939 Kbps This is the spare bandwidth that a TLAN should have to handle the VoIP and fax traffic. Nortel Networks recommends that the TLAN handle Remote Office traffic exclusively. Note: This example is based on the G.729 Annex AB codec with 30 ms payload size.
Page 407 March 2000 Network engineering guidelines WAN links are normally based on PSTN standards such as DS0, DS1, DS3, SONET STS-3c, or Frame Relay. These standards are full-duplex communication channels. With standard PCM encoding (G.711 codec), a two-way conversation channel has a rate of 128 Kbps (that is, 64 Kbps in each direction). The same conversation on WAN (for example ISDN PRI) requires a 64 Kbps channel only, because a WAN channel is a full duplex channel.

Page 410 Traffic between the two sites can be broken down to 54 CCS from Santa Clara to Richardson, and 46 CCS from Richardson to Santa Clara, with the voice traffic 40 CCS (=60-20) being the two-way traffic. Remote Office 9150...
Page 411 March 2000 Network engineering guidelines The bandwidth requirement calculation is (40/36)*11.2 + (14/36)*33.6 = 25.51 Kbps where 14 CCS is the larger of two fax traffic parcels (14 CCS as compared to 6 CCS). After adjusting for peaking, the incremental data rate on WAN for this route is 33.2 Kbps.
Page 412: Assessing Wan Link Resources
A visual inspection of the topology map should reveal which WAN links are likely to be used to deliver Remote Office traffic. Note: For an example, see the network topology map on page 387.

Page 415 March 2000 Network engineering guidelines Estimating network loading caused by Remote Office traffic At this point, you have enough information to “load” the Remote Office traffic on the intranet. The “Network topology map” on page 387 illustrates how this is done on an individual link.

Page 417 March 2000 Network engineering guidelines Determining if there is enough capacity The following table arranges the calculations so that for each link, the available link capacity can be compared against the additional Remote Office load. For example, on the link between Router 4 and Router 5, there is plenty of available capacity (492 Kbps) to accommodate the additional 24 Kbps of Remote Office traffic.

Page 429: Measuring The Intranet Quality Of Service
March 2000 Network engineering guidelines Measuring the intranet Quality of Service Introduction You can measure end-to-end delay and error characteristics of the current state of the intranet. These measurements help you set acceptable QoS standards when using the corporate intranet to transmit voice services. Measuring end-to-end network delay The basic tool used in IP networks to measure end-to-end network delay is the ping command.
Page 430 The ping statistics are based on round trip measurements, whereas the QoS metrics in the Transmission Rating model are one-way. In order to make the comparison compatible, the delay and packet error ping statistics must be halved. Remote Office 9150...
Page 431 Packets that arrive outside of the window allowed by the jitter buffer are discarded by the MIG RLC or the Remote Office 9150 unit. To determine which ping samples to ignore, first calculate the average one-way delay based on all the samples and then add 500 ms.
Page 432 “excellent” service level is likely to be upheld. Other measurement considerations The ping statistics described previously measure the intranet prior to Remote Office installation, which means that the measurement does not take into consideration the expected load offered by the Remote Office users. Remote Office 9150...
Page 433 March 2000 Network engineering guidelines If the intranet capacity is tight and the Remote Office traffic is significant, you should consider making intranet measurements under load. Load can be applied using traffic generator tools. The amount of load should match the Remote Office traffic estimated in “Remote Office traffic engineering”...
Page 434 Components of delay End-to-end delay is contributed by many delay components. The major components of delay are propagation delay serialization delay queuing delay routing and hop count Remote Office system delay router processing delay LAN segment delay Remote Office 9150...
Page 435 March 2000 Network engineering guidelines Propagation delay Propagation delay is affected by the mileage and medium of links traversed. Within an average size country, the one-way propagation delay over terrestrial lines is under 18 ms. Within the United States, the propagation delay from coast- to-coast is under 40 ms.
Page 436 The diagram on page 410 displays the average queueing delay of the network based on a 300-byte average packet size. Queuing delay of various links Queueing delay of various links Delay (ms) Utilization 64 Kbps 256 Kbps 128 Kbps 512 Kbps G101426 Remote Office 9150...
Page 437 March 2000 Network engineering guidelines As you can see, queueing delays can be significant for links with bandwidth under 512 Kbps, whereas with higher speed links, they can tolerate much higher utilization levels. Routing and hop count Each site pair takes different routes over the intranet. The route taken determines the number and type of delay components that add to end-to-end delay.

Page 441 March 2000 Network engineering guidelines Routing issues Routing irregularities can introduce unnecessary delay. A routing implementation can overlook a substantially better route. A high delay variation can be caused by routing instability, misconfigured routing, inappropriate load splitting, or frequent changes to the intranet. Severe asymmetrical routing results in one site perceiving a poorer QoS than the other.
Page 442: Implementing Quality Of Service In Ip Networks
Another approach is to consider using QoS mechanisms in the intranet, the goal of which is to provide a more cost-effective solution to engineering the intranet for non-homogenous traffic types. Unfortunately, IP QoS mechanisms are still relatively new, hardly implemented on intranets, and difficult to predict the consequences. Remote Office 9150...
Page 443 March 2000 Network engineering guidelines This section outlines what QoS mechanisms can work in conjunction with the Remote Office node, and with what new intranet-wide consequences if implemented. Traffic mix Before implementing QoS mechanisms in the network, you must assess the traffic mix of the network.
