Voice Trunk Line Part

The voice trunk line part is configured with digital trunk lines and analog trunk lines.

TEPRIa/TEPRI2 functions as E1, T1 and Primary Rate Interface (PRI) digital trunk line on

a module, sends/receives voices through the trunk line and transmits the data information

of 64 kbps per channel. The 8Trunk (8TRK),8TRK2,16TRK functions as Polarity Reverse

Detection (PRS) and Caller ID (CID) provides the Metering Pulse Detection function in

option. (The 8TKR2/16TRK do not support the MPD function)

In addition, it sends/receives voices as analog trunk line function and transmits the data

information of 64 kbps per channel.

Voice Station Part

The voice station part is configured with Digital Line Interface (DLI), which is a digital

station, and Subscriber Line Interface (SLI), which is an analog station, and provides voice

services and provides the voice service. Multiple station modules can be mounted

depending on the combination of port numbers and stations. Examples of the digital station

have the 16DLI2 and 8DLI modules. Those of the analog station have the 16MWSLI and

16SLI2, 8SLI2 modules.

In addition, the combo-type 8COMBO2 which is the combination of analog and digital

stations, exists.

Data Transmission Part

The data module is configured with the GWIMT, which is a WAN interface module, and

the LIM/PLIM/PLIM2/GSIM /GPLIMT/GSIMT, which is a LAN interface module. The

LIM/PLIM/PLIM2 module sends or receives data to/from internal Intranet, provides

10/100 BASE-T interface and functions as a switching hub.

The PLIM/PLIM2 module provides the Integrated Power over Ethernet (Integrated PoE)

function. The GPLIMT provides the Layer 2 LAN interface to support internal data

networks and serves 10/100 BASE-T Fast Ethernet (FE) and 1000 BASE-TX/SX/LX

interface for data transmission (GPIMT supports 10/100 BASE-T FE and 10/100/1000

BASE-TX). The GSIM/GSIMT module provides the Gigabit LAN interface of Layer 2 and

Layer 3 to support data networks and serves the 1000 BASE-TX/SX/LX interface (GSIMT

only supports 10/100/1000 BASE-TX).

The GWIMT, which is a Gigabit router board for data communication with external

Internet, provides the WAN interface to support data networks.
