A Meridian 1 IP Enabled (IE) Option 81C 25.40 system provides wired service via a combination of i2004 Internet Telephones and M3900 handsets. Four 802.11 Internet Telephony Gateway (ITG) wireless cards are installed in an Intelligent Peripheral Equipment (IPE) shelf on the Meridian 1 IE to provide wireless access via IP enabled wireless handsets. To configure each port on the 802.11 ITG wireless card, what should the “TYPE” parameter be set to in Overlay (LD) 11 to allow proper functioning of the IP enabled wireless handsets?

A Meridian 1 IP Enabled (IE) Option 81C 25.40 system provides wired service via a combination of i2004 Internet Telephones and M3900 handsets. Two 802.11 Internet Telephony Gateway (ITG) wireless cards are installed in an Intelligent Peripheral Equipment (IPE) shelf on the Meridian 1 IE to provide wireless access via IP enabled wireless handsets. Following the required procedures, a new 802.11 ITG wireless card is configured. One of the steps requires transmitting the configuration data from the Optivity Telephony Manager (OTM) PC to the 802.11 ITG wireless cards. In preparation to transmit the configuration data to the 802.11 ITG wireless cards, all 802.11 ITG wireless cards are disabled in the
Meridian 1 IE system.
The following steps are then taken:
The “IP Telecommuter” window on the OTM PC is opened and a card is selected.
The configuration data (node, card, and Gatekeeper properties) is transmitted to the selected card.
When the configuration data is successfully sent, the window is closed.
The “IP Telephony Gateway” main window is refreshed to show the status of the selected card.
Replace the 802.11 ITG wireless card.
Reboot the 802.11 ITG wireless cards.
Re-enable the 802.11 ITG wireless cards.
Verify the TN, MAC, and IP addresses for each 802.11 ITG wireless card.
Four 802.11 Internet Telephony Gateway (ITG) wireless cards are provisioned in the Meridian 1 IP Enabled (IE) Intelligent Peripheral Equipment (IPE) shelf. During the normal course of operation, you notice a voice channel on one of the 802.11 ITG wireless cards has a consistent voice quality fault such as persistent noise or lack of voice path. The problem persists even after reseating the 802.11 ITG wireless card and retransmitting the card properties via Optivity Telephony Manager (OTM). During the boot sequence, an I303 message displays on the faceplate and the 802.11 ITG wireless card resets before completing its reboot. The I303 message does NOT display on every reboot of the 802.11 ITG wireless card. The I303 message indicates that the DSP subsystem failure initialing card reboot. What is your next action?
Ensure that the boot file is NOT corrupted.
Perform a reboot of the 802.11 ITG wireless card.
Attach an OTM PC to the maintenance port and analyze the error logs.
Ensure that the Telephony LAN (TLAN) Ethernet cable is firmly connected to the faceplate.
Four 802.11 Internet Telephony Gateway (ITG) wireless cards are provisioned in the Meridian 1 IP Enabled (IE) Intelligent Peripheral Equipment (IPE) shelf. During normal maintenance action the Optivity Telephony Manager (OTM) fails to establish connection with one of the 802.11 ITG wireless cards. The faceplate of the 802.11 ITG wireless card reads BIOS. The command is sent to reboot the BIOS and the following observations and steps are noted:
The boot sequence indicates that the BIOS is being loaded:
Jumping to romStart at 0x00E00300.
Booting from BIOS ROM.
An attempt is made to reload the software from the OTM host.
The software reload to flash memory is successful and the card is rebooted.
However, the ITG software fails to load into RAM. What is your next action?
Reboot the BIOS.
Reseat the 802.11 ITG wireless card.
Check the maintenance display and attempt to format the drive.
Click the "Open Log File" on the Maintenance tab of the ITG Card Properties for analysis.
A Meridian 1 IP Enabled (IE) Option 81C 25.40 system and a Meridian SL-100 system are to be connected via ISDN Primary Rate Interface (PRI) links. The trunk hunt sequence is set to “ASEQ” (hunt from first to last trunk) in the Meridian SL-100. Glare occurs when two offices simultaneously select the same trunk members of a two-way trunk group for two different calls. What should the "SRCH" sequence be set to in the Meridian 1 IE to combat the possibility of "glare"?
CCW (counter clockwise)
MIDL (most idle)
RRB (round robin)
A multisite Meridian 1 IP Enabled (IE) Option 81C 25.40 system and a Meridian SL-100 system will be interworked. The “DRAT” parameter in the Meridian 1 IE is set to “64KC”. Similarly, the “DCHRATE” and “HDLCTYPE” parameters in the Meridian SL-100 are set to “64K" and "HDLC”. What must the “LCMT” parameter be set to in the Meridian 1 IE to support this functionality?
A Meridian 1 IP Enabled (IE) Option 81C 25.40 system and a Meridian SL-100 system are connected via ISDN Primary Rate Interface (PRI) links. During the initial activation, a few links generate these messages:
DTA 018 Frame-slip out-of-service limit
DTA 021 Loss-of-frame-alignment for 3 seconds What should you do?
Perform a PRI status check.
Contact the far-end to initiate a loop-back test.
Check that Meridian 1 IE parameters match the far-end parameters.
Use the Error Counter to verify the 1.5 Mbps digital transmission from the PRI to each connection.
During a software upgrade on a Meridian 1 IP Enabled (IE) Option 61C or 81C system, when is it normal for a service interruption?
Switching to the inactive CPU.
Running CPU and memory tests.
Switching to an inactive Network Group.
Running the software installation program.
Nortel recently added several IP telephony certifications to its lineup, including two expert-level certifications and two certifications aimed at those who design networks that use the vendor's products.
There are two main tracks: the Nortel Networks Certified Support Specialist (NNCSS) and Nortel Networks Certified Design Specialist (NNCDS).
Targeted at entry-level to mid-level IT pros who work in support roles, NNCS measures validates skills in installing, maintaining, and configuring Nortel products. The NNCDS, on the other hand, is targeted at those who design and plan networks that use Nortel products. Both tracks offer separate certifications for the CallPilot 2.0, VoIP Meridian 1 IP Enabled 25.40, VoIP Succession Business Communication Manager 3.0, and VoIP Succession CSE 1000.
Here's a quick glance at the newest offerings:
* Support Expert- IP Convergence CallPilot 2.0 Unified Messaging Solutions: This requires CallPilot 2.0 Unified Messaging Solutions exam 920-466, as well as IP Convergence exam 920-802. Candidates must first hold the NNCSS in CallPilot 2.0 prior to taking the latest exam.
* Support Expert- IP Convergence Meridian 1 IP Enabled 25.40: The required exam, ">920-456, was scheduled to be released on June 3. Like the other expert-level certification, candidates must take the IP Convergence exam 920-802 and hold NNCSS certification for the Meridian platform.
* Design Specialist certification for VoIP Succession Business Communication Manager (BCM) 3.0: This certification requires the Succession BCM 3.0 exam, 920-125, along with the VoIP Technology exam, 920-801.
