ICB Release 4 20 June 2007

18 Product description

The ICB card provides announcements and tones that relate to speciﬁc events during conferences. These events include the following:

•

advising the chairperson and conferees of the status of the conference connection

•

indicating when a conferee joins or leaves the conference, and

•

warning the chairperson and the conferees when the conference is about to expire.

Technicians can install multiple ICB cards into:

•

a Media Gateway chassis shelf for a CS 1000

•

an Intelligent Peripheral Equipment (IPE) shelf for a Meridian 1/CS 1000

•

an Option 11 shelf

•

an IPE shelf for a CS 2100/Meridian SL-100

Each ICB card can operate independently, providing up to 32 ports for a single conference. The ICB card can support up to ten simultaneous, separate conferences.

When users establish a single-card conference, they use the 32 ports on the card. If two conferences are held at the same time, they need to share the 32 ports. For example, if one user sets up a 10-port conference, the other can set up a 22-port conference.

Technicians can connect two ICB cards to provide up to 62 ports for a single conference. In dual mode, there can be only one dual-card meeting per pair of cards. The user database and access numbers are not shared in a dual-card conﬁguration. There is a separate access number required for a dual-card meeting.

The ICB supports several simultaneous conferences. The number of conferences depends on the number of ICB ports available and the number of participants (conferees) in each conference. Each ICB card supports the following:

•

maximum number of participants as follows: — single-card: 32 participants — dual-card: 62 participants (unless Chairperson Control over a

Dual-card Meeting is activated, in which case it is 60 participants)

•

any number of conferences (up to 10) with one or more participants in each conference

ICB Release 4 20 June 2007

ICB description 19

The ICB communicates with the system software by emulating a digital line card (XDLC), which allows existing software to control the operation of the ICB. Conﬁgure each ICB port as an Automatic Call Distribution (ACD) M2616 digital telephone set.

System overview

The ICB comes as a single card, or a pair of cards if additional ports are required to support a dual-card meeting. Each card stands alone, even in the dual-card conﬁguration. For dual-card meetings, the primary card uses ports on the secondary card. The following rules apply:

•

Each card (that is, the primary and secondary) has its own set of users. There is no "common list" for both cards.

• To schedule a conference, the user logs into the card in which their

account is deﬁned. If the user has two accounts, one on each card, they must try each card separately to ﬁnd available resources for the conference. There is no automatic pooling between cards.

•

A user, super-user, or executive-user can have accounts on many cards at a company (that is, a customer can have one person who administers multiple bridges for their company).

•

Dual-card conferences can only be scheduled by users on the primary card.

ICB conference feature summary

•

The ICB faceplate provides the following: Maintenance LED - The ICB faceplate provides a red LED to indicate the

enabled/disabled status of the card and to indicate the self-testing result during power up or card insertion into an operating system. This LED indicates the following:

•

The LED is lit when the ICB card is disabled.

•

The LED is off when the ICB card is enabled and ready for use.

• The LED blinks three times, runs software from the PCMCIA, then blinks three times again and stays on. The LED remains on until the software is enabled when the ICB card successfully completes the self-test.

PCMCIA activity indicator LEDs - These LEDs are next to the PCMCIA slots and indicate the following:

•

The LED is lit when the PCMCIA card is disabled.

• The LED is off when the PCMCIA card is enabled and ready for use.

External equipment

VT100 type terminal

Use a VT100 terminal for initial card conﬁguration. After initial card conﬁguration, use the BUI to perform operations, administration and maintenance (OA&M). Connect the terminal to the ICB RS-232 interface using one of the following methods:

•

Direct connections: — directly to the IPE module I/O panel — directly to the DB-9 connector on the NT5D52 Ethernet Adapter

card installed on the I/O panel

•

Remote connections: — to the IPE module I/O panel through a modem connection

The terminal interface must be set at 9600 baud, 8 data bits, 1 stop bit, and no parity. The ﬂow control is hard wired (do not use XON/XOFF ﬂow control).

Ethernet application

ICB Ethernet use has the following characteristics:

•

The ICB Ethernet connection is separated from the external LAN trafﬁc by a ﬁrewall.

•

The Ethernet Adapter connection for ICB is NT5D52AA for the IPE module application.

•

The Ethernet provider assigns the IP address for the ICB. Enter the IP address from the Maintenance terminal.

•

To access the ICB CLI over the Ethernet, use a TELNET client on a PC workstation or in the LAN.

ICB operation

The ICB provides ﬂexibility in conﬁguring conferences. Conﬁgure conferences as follows:

•

pre-scheduled conferences with a ﬁxed number of ports and start/stop times

NN43001-558/555-4001-135 01.02 Standard

ICB Release 4 20 June 2007

ICB operation 27

•

pre-scheduled conferences with a variable numbers of ports, where ports are added when required (if available) and subtracted by the system automatically as conferees leave the conference

•

permanent bridges with ﬁxed numbers of ports that can be used without pre-scheduling the conference

The minimum duration of a conference is 15 minutes and the maximum duration of a time-limited conference is 12 hours. The conference starting time and duration can be scheduled in increments of 15 minutes.

The ICB card continuously monitors the audio signal level received from each conferee and selects the two loudest signals for transmission. The two loudest signals are summed and inserted into the PCM sample prior to their transmission to other conferees. This implementation of the two loudest signals improves the interrupting capability of a conference connection and allows normal two-way conversation that all conferees can hear.

In addition to the conferee timeslots, the ICB provides a timeslot between the MPU and the DSP. This timeslot transmits message prompts, entry and exit tones, or both that the system broadcasts to all conferees when requested by the MPU.

The ICB uses ACD features to route external incoming trunk and local line conferees to their appropriate conferences. The ACD features provide queuing, chairperson features, and event reporting for each conference.

The ACD features used by the ICB card provide the following:

•

easy software conﬁguration

•

incoming calls, announcement on arrival, call management, and reporting queues

•

operational statistics reports

•

enhanced call routing

Figure 3 "Call routing with chairperson access" (page 28) shows the call

routing for three conferences and shows the conference chairperson access DN for each conference. The ﬁgure also shows the ACD DN for the ACD queue that controls the path of all ports on an ICB card. The right-hand side of the ﬁgure shows the distribution of ICB ports as ACD agents.

Figure 3 Call routing with chairperson access

Join the conference using the direct meeting access method

Assign a main DN and a chairperson DN, for each conference. The main DN is the number the conferees dial to get into the conference and the chairperson DN is the number the chairperson dials. Conﬁgure the DNs in the Meridian/CS 1000 system when installing the ICB card. The total number of DNs is equal to two times the number of simultaneous conferences. For example, 10 simultaneous conferences require 20 DNs: 10 main DNs and 10 chairperson DNs.

When several conferences occur simultaneously in the same ICB card, the conferee dials the DN assigned to a speciﬁc conference. The ICB card identiﬁes the dialed DN and routes the conferee to the appropriate conference represented by that speciﬁc DN. The system assigns all ports on the ICB card to the appropriate conference through the ACD DN assigned

to that ICB card. The chairperson dials the chairperson DN to a speciﬁc conference. This number is different from the DN dialed by the conferees for the same conference.

The ICB performs DTMF detection on ICB ports identiﬁed as chairperson ports. DTMF detects when conferees enter a conference password. A conference can start without the chairperson. If all allocated ports for a conference are taken up with conferees, the chairperson cannot join the conference, unless a port is speciﬁcally reserved for the chairperson. The chairperson can also join if the system allows conference expansion and there are free, un-scheduled (ﬂoating) ports available.

The ﬁrst conferee joining the conference hears an announcement indicating that no other conferee has joined the conference, followed by 60 seconds of music. The system repeats the announcement with 60 seconds of music, until another conferee joins the conference.

Join the conference using the single DN access method

The single DN access method to all meetings provides users with a alternative method of accessing the ICB. This feature reduces the amount of Direct Inward Dialing (DID) numbers that have to be conﬁgured in the switch and provides the following beneﬁts:

•

Saves 20 DID numbers from the customer’s DID range.

•

Saves 20 ACD or Phantom DNs in the Meridian system thereby providing a cost savings.

•

Simpliﬁes installation as there is no DN pair conﬁguration.

•

Saves work if a change in the numbering plan is required in the Meridian system.

The only trade-off is that callers have an additional step when accessing a meeting (that is, after dialing the single-access DN, they must enter the chairperson, or meeting, DN of their speciﬁc meeting).

Figure 4 "Single DN access method (one ICB card)" (page 30) shows the

DN conﬁguration for single DN access with one ICB card.

Figure 4 Single DN access method (one ICB card)

The DNs on the left in Figure 4 "Single DN access method (one ICB card)"

(page 30) can be Phantom DNs or CDNs, instead of ACD DNs. The DNs

must be DID numbers. In a dual-card system, each card requires its own single-access DN. In a

dual-card set, conferences that span the two cards do not support the single DN access method. However, in a dual-card set, simple conferences that use only one card support the single DN access method.

Figure 5 "Single DN access method (two ICB cards)" (page 31) shows the

DN conﬁguration in a Meridian system for the single DN access method when the system uses two ICB cards. Single DN access requires one DN, instead of the separate 10 DNs required with direct meeting access.

The ﬁgure shows a conﬁguration that supports the following:

•

Simple conference contained in the primary ICB - participants dial the single-access DN at the top of the ﬁgure.

•

Simple conferences contained on the secondary ICB - participants dial the single-access DN at the bottom of the ﬁgure.

•

Meetings spanning both cards - participants dial the "Dual meeting main DN" in the middle of the ﬁgure and the chairperson dials the "Dual meeting chairperson DN". The ﬁgure shows that dual-card meetings do not use the single-access DNs.
