  • Page 20 Connecting a telephone set to a port reserved for Bridge Port invalidates Bridge Port operation Do not connect a telephone set to the port that is going to be used as a Bridge Port. This causes the Bridge Port to fail.
  • Page 21 9150 unit or a Remote Office 911x series unit. Free-standing key system Nortel Networks does not support a Remote Office system as a free-standing key system. If you are searching for free-standing key systems, inquire about the Norstar and Business Communications Manager product lines.
  • Page 22 Multiple DN appearances are not supported for local calling on the Remote Office 9150 unit. Therefore, you cannot configure the same DN to local calling keys on multiple digital telephone sets connected to one Remote Office 9150 unit.
  • Page 23 DSP channel. The following example assumes one 16-port RLC with no additional DSP Application Modules for an RLC with eight DSP channels. While one telephone call is active, which uses one DSP channel, a call to an MCR key assigned to eight Terminal Numbers (TNs) produces a DSP allocation error.
  • Page 24 QoS transition recovery Due to the requirement to support on-demand routers, the IP network is not continually tested during QoS transition situations. It is tested only when there are active voice calls over ISDN. As a result, transitioning needs active calls for the user-configured recovery period in order to switch back to IP.

  • Page 25: Impact Of Delay On Voice Quality

    Impact of delay on voice quality The impact of the different voice algorithms (G.729A, G.726, and G.711) is well documented. G.729A provides 8 to 1 compression and does not produce perfect voice quality. Most users consider it quite acceptable, although some users claim that they can hear the difference between it and G.711.
  • Page 26 The following table indicates one-way delay in ms for the common configurations. It can seem unusual that the ISDN delay is larger than the IP delay. However, this is due to the serialization delay of sending the packets across the relatively low-speed (64K) channels provided by ISDN. (The IP Network delay assumes high-speed Internet access as part of the intranet.) Minimum recommended jitter buffer setting...

  • Page 27: Pstn Testing

    In both cases, you can perform the tests on a specified Remote Office 9150 unit for a specified range of data ports on the RLC. When using the disruptive mode, Nortel Networks recommends that you wait two or three minutes between tests to give the Remote Office system time to recover.

  • Page 35 9150 unit. If the calls are not answered after the transfer, the calls are placed in that users personal voice mailbox. Local BRI calls ring the local keys of a reception telephone (L2000). When answered, these calls transfer to other DNs on the Remote Office 9150 unit (3000).
  • Page 36 Scenario 4 9150 All local inbound calls pass immediately to the host PBX and then are “trombone” re-directed to the Remote Office 9150 units user’s primary PBX DN key. ATTENTION Disable DN Discovery. This forces the Remote Office 9150 unit to use local DNs (non-PBX DNs) and does not replace the local DN with the primary PBX DN.
  • Page 37 Calls to this DN alert the user’s Remote Office 9150 unit digital telephone set. They pass from the BRI to the Bridge Port, trombone to the host PBX, then to the primary DN on the user’s digital telephone set. If the digital telephone set is busy, regular call treatment occurs, including directing the call to the user's voice mailbox.

  • Page 38: 9150 Bri Configuration Property Sheet

    9150 BRI Configuration property sheet This topic provides important information about the BRI Configuration property sheet. To access this property sheet, go to Configuration Manager BRI Configuration. Disabling Multiple Subscriber Number (MSN) Remote Office requires the ISDN numbers to be unique per module for PSTN connections between the RLC and Remote Office 9150 unit.

  • Page 39: Local Remote Office 9150 Unit Dialing Plan

    Local Remote Office 9150 unit dialing plan The Remote Office 9150 unit discovers the DN numbers of the local digital telephones either through DN Discovery or configuration. The Bridge Ports, Local Calling, and Local SwitchOver features depend on this knowledge as follows: If a call has an appearance on a Local Calling key, the Remote Office 9150 unit first attempts to complete the operation (for example, call, transfer,...

  • Page 40: Operation (Remote Office Units)

    9150 unit sends a transparent Not Ready key press to the host PBX and places the ACD agent’s digital telephone set in Not Ready mode. This feature prevents the ACD agent from receiving calls when active on a local call. The Remote Office 9150 unit removes the digital telephone set from the Not Ready mode when the agent terminates the local call.

  • Page 41: Analog Ports

    Remote Office units connected to Meridian SL-100 PBXs does not produce a dial tone. The digital telephone sets operate properly, but no dial tone is present. To produce dial tone in this situation, configure the port on the RLC as a TAPI port.
  • Page 42 Classless Inter-Domain Routing (CIDR) not supported Remote Office does not support Classless Inter-Domain Routers (CIDRs). For more information, refer to “Remote Office 911x series unit telephone set menu allows CIDR configuration (Q00609432)” on page 57. Configuration Manager access of Remote Office devices not possible...
  • Page 43 MADNs, refer to “Multiple Appearance Directory Number (MADN),” on page 23. When placing a telephone call, the dial tone is delayed from the time that the user goes off-hook. The duration of this delay depends on the number of simultaneous calls actually being set up.

  • Page 44: Distinctive Ring

    Also, measure the line loss and compensate using the trunk class of service NTC or TRC as required. Nortel Networks recommends that the trunk card be an enhanced version (EXUT). An EXUT supports more complex impedance situations. Please refer to NTP 553-3001-106 for trunk cards and the NTP for your specific PBX for more information.

  • Page 45: Emergency Service Programmability

    If you downgrade the host PBX to a release prior to X11 Release 25.40, you must also downgrade any new or upgraded M39xx digital telephone sets so that the Meridian 1 can support them. This applies to digital telephone sets attached to Remote Office units and Extended Digital Line Cards.
  • Page 46 Idle set display message does not get updated When you update the message on the host PBX that displays when the digital telephone set is idle, you must unplug the digital telephone set and plug it back for the change to take effect.
  • Page 47 Remote Office 9150 unit, the logon process takes longer than expected if a headset is not plugged into the digital telephone set. Initialization of the digital telephone set under these conditions can take up to one minute. NAT routers Translation tables within NAT routers control the communication path from the private network to the public network.
  • Page 48 Phase I M3905 digital telephone sets receive false messages during a re-boot of the Remote Office 9150 unit and can lock up. Unplug and re-plug the telephone cord at the wall jack or perform a system shutdown and re-power up the Remote Office 9150 unit to recover.

    After DSP Limit error messages appear on the displays of digital telephone sets connected to Remote Office units, the messages do not clear. To clear the display, press the Release (Rls on some digital telephone sets) key or lift the handset when the error no longer exists.
  • Page 55 M3905 digital telephone sets do not play tone B for a second incoming call (Q00557165) If an M3905 digital telephone set is on a call when another call comes in, it does not alert the user by playing tone B. The only indication that the user has of a second incoming call is the flashing of the call indicator.
  • Page 56 ID. You must unplug the digital telephone set and plug it back in to get the key labels to re-appear. Sometimes you must unplug the digital telephone set and plug it back in a second time to restore the functionality to all the keys.
  • Page 57 No audible DTMF tones sent on Local Switchover calls (Q00591233) With Local Switchover enabled, the Remote Office system does not relay DTMF tones to called local digital telephone sets. To relay DTMF tones on local calls, you must either disable Local Switchover or use speed dial to send the desired digits.
  • Page 58 Remote Office 911x series units only dial 20 digits pulled from the PSTN Number to Connect to RLC field (Q00615074) Remote Office Configuration Manager allows administrators to configure up to 30 digits in the PSTN Number to Connect to RLC field. However, the Remote Office 911x series units only dial the first 20 digits in this field when trying to establish a connection to the RLC.
