· ACD (Automatic Call Distribution) – automatically distributes the call
depending on the most idle agent – suitable for call center – need to capture the
reports.
BASIC CARDS

FALC: Flexible Analog Line Card – 16 Ports (-40 V DC)
MWLC: Message Waiting Line Card – 16 Ports
XCOT-I : Trunk Card India Modified – 8 Ports
COT/PPM: Trunk Card – 8 Ports
UNVTRK: Universal Trunk Card – 8 Ports
PRI: Primary Rate Interface (2 types) – 30B + 1D: E1 & 23B + 1D: T1
DTI: Digital Trunk Interface (2 types) – 30 Channels: E1 & 24 Channels: T1
MIRAN: Meridian Integrated RAN
MICB: Meridian Integrated Conference Bridge
E & M: Ear & Mouth Card
PRI Card
· Need to configure a D-Channel
· EURO, Q Sig, ESS4, SL1 – Protocols Between switches by which data can be
sent thru D Channel
· Outband Signaling – Signaling has a separate channel (CCS- Common Channel
Signaling)
· All signals are passed via D-Channel
· The line remains idle as long as acknowledgement is not rxed although the call
is placed
DTI Card
· Inband Signaling
· Channel Associated Signaling (CAS) – No Protocol
· Two types of Condition: Idle & Seize Code - should match in remote end
· All signals passed in the same Voice Channel
· Once the call is placed the line is seized & that extn becomes busy for Other
Callers.
MITG (Meridian Integrated (IP) Telephony Gateway)
· Voice over IP – Extending ur voice in network over Internet
· Two Types : (1) Line side (using IP Phone over WAN)
(2) Trunk side (Connect two meridian over Ethernet)
· ITG – TDM to convert IP Packets & Compresses data

· ITG 1.0 – 8 simultaneous calls – occupies 2 slots
· ITG 2.0 – 24 simultaneous calls – occupies 2 slots – OTM 2.0 or later
· ITG 3.0 – 32 simultaneous calls – occupies 1 slot – OTM(Optivity Telephony
Management) 2.0 or later – MC (Media Conversion) Card
· MAT (Meridian Administration Tools) 6.1 or later – PC with Windows 95 or
later


Has 2 Ethernet ports, one is for E LAN & one is for T LAN Connection

MITG Trunk Configuration
· ITG Command Line Interface Configuration : E LAN Configuration of MITG
Login as: itgadmin
Pwd: itgdmin
At ITG >setLeader “xx.xx.xx.xx”,”yy.yy.yy.yy”,”zz.zz.zz.zz” <Enter>
xx.xx.xx.xx: IP Address of Management interface
yy.yy.yy.yy: Gateway IP Address of Management interface on the leader 0
zz.zz.zz.zz: Subnet mask for the Management Interface
After this, reboot ITG Card & after which LCD Display on front of ITG
Card will indicate BLDR (Backup Leader)
