Meridian Integrated Personal

Call Director (MIPCD) Music File:

The current software release on the

MIPCD is 1.5. When the “one number”

is called and the MIPCD begins to

search for the user based on the

“follow me” profile, music is played. At

present the music being played is a

“fixed” program in that it must be used

and no alternate file can be loaded to

the MIPCD. Customized music files

cannot be used until Release 2 which

is planned to be released in 2Q/04.

The music file that is about 1 minute in

duration will be approximately 1MB in

size.

INTEROPERABILITY OM5000 ITU CWDM OMX and Finisar OADM The Nortel Networks OM5000 ITU CWDM OMX provides a superior alternative to the Finisar CWDM Optical Multiplexer (OMUX). The OM5000 CWDM OMX is available in a 4-port or an 8-port version, and provides the following advantage over the Finisar OMUX’s: 1. Significant reduction in price 2.

Calculations per wavelength The link budget has to be calculated for every wavelength. The following should be included: The two most common protocol mappings for Fiber Channel are FCP, which is SCSI over FC and FC-SB2, single byte command code set for FICON. • FICON comes as an ESCON evolution and is based on the Fiber Channel Standards.

NETWORK MANAGEMENT Installing Preside Trail Manager from the Hard Disk Trail Manager 4.2.4 Service Pack 1 is distributed on CD-ROM and is typically installed in this format at customer locations. The user documentation details the installation procedure (in the Trail Management 4.2 SP1 Administration Guide NTP 450-3101-094) from CD-ROM.

with a rule to mark all IP as EF. Make sure the user profile has default setting “excess action: Mark”. prevents successful reassembly of an egress frame. This can occur for two principal reasons: ¾ ¾ An 802.3x PAUSE frame was received on an Ethernet link, and queued egress traffic depleted available buffer space while the pause function timer was counting down or before a 0pause_time PAUSE frame (which would resume transmission) could be processed.

OctaPID’s buffer space than a single queue used by unmarked (or uniformly marked) traffic. including the VLAN Id and the Ethernet port priority which are dynamically configured on the port. Outloss Packets counters presently have no MIB object and cannot be polled using SNMP. 802.1x uses Extensible Authentication Protocol (EAP) which provides a generic transport mechanism for support various authentication protocols.

collisions. Once a Client determines that the channel is clear it will wait a random period of time before transmitting in order to decrease the probability that two Clients will transmit at the same time which would result in a collision. the AP experiencing minimal interference AP thereby communicating using the highest basic data rate. Again, not realistic but understanding the limits of WLAN performance is useful when designing WLAN networks.
