CHAPTER 1. Overview of OfficeServ 7400
Voice Trunk Line Component
The voice trunk line component is configured with digital trunk lines and analogue trunk
lines. T1E1PRI (TEPRI)/TEPRI2 functions as an E1, T1 and Primary Rate Interface (PRI)
digital trunk line module, sends/receives voice data through the trunk line and transmits the
information at 64 kbps per channel. The 8Trunk (8TRK) functions as Polarity Reverse De-
tection (PRS) and Caller ID (CID) provides the Metering Pulse Detection function option.
In addition, it sends/receives voice data as analogue trunk lines and transmits the in-
formation at 64 kbps per channel.
Voice Station Component
The voice station component is configured with Digital Line Interface (DLI) (digital sta-
tions) and Subscriber Line Interface (SLI) (analogue stations) and provides voice services.
Multiple station modules can be installed depending on the combination of port numbers
and stations. Digital stations have the 16DLI2 and 8DLI modules; analogue stations have
the 16SLI module.
Additionally, there is the 8COMBO, a combination of analogue and digital stations.
Data Transmission Component
The data module is configured with the GWIM, a WAN interface module, and the
LIM/PLIM/GLIMP/GSIM LAN interface modules. The LIM/PLIM modules send or re-
ceive data to/from the internal Intranet, provide a 10/100 BASE-T interface and function as
a switching hub. The PLIM module provides the Integrated Power over Ethernet (PoE)
function.
The GPLIM module provides the Layer 2 LAN interface to support internal data networks
and serves the 10/100 BASE-T Fast Ethernet (FE) and 1000 BASE-TX/SX/LX interface
for data transmission.
The GSIM 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. The GWIM, a module for
data communication with the external Internet, provides the WAN interface to support data
networks. The 4 Digital Subscriber Line (4DSL) module provides services to data sub-
scribers up to 1 km away from the internal Intranet. Subscribers can use Ethernet services
within the transmission distance of 1 km.
