3.12.6 Connecting the Interface Cable
Caution:
If outdoor cabling is involved, consider to install a special lightning arrester at the input
end of the interface cable for better lightning protection.
Before you connect a port, read its label carefully; a wrong connection can cause
damages to the interface card and even the device.
Step 1: Identify the to-be-connected port on the MIM-4BSE.
Step 2: Identify the type of the ISDN line provided by your telecommunications service
provider.
Step 3: Connect the cable.
z
For an ISDN U interface line, adapt the interface with an NT1 by inserting one end
of the S/T interface cable into the S/T port on the NT1 and the other end to the BRI
port on the MIM-4BSE.
z
For an ISDN S/T interface line, directly connect the cable to the BRI port on the
MIM-4BSE.
3.13 MIM-1G.SHDSL
3.13.1 Introduction
1-port Single-Pair High-Speed Digital Subscriber Line module (MIM-1G.SHDSL) adopts
the Trellis Coded Pulse Amplitude Modulation (TCPAM) approach and can provide the
symmetric speed as high as 2.3 Mbps. Its transmission speed can automatically adapt
to cable length and conditions. Compared with ADSL, G.SHDSL allows longer
transmission distance and as such, can serve a wider range of applications. It can
substitute for E1/T1 lines to provide high-speed data service access. However, as
TCPAM uses the band starting from 0 Hz for data transmission, G.SHDSL cannot share
the same line with POTS or ISDN just like what ADSL has done.
The MIM-1G.SHDSL module supports:
z
Manual G.SHDSL line activation/deactivation and easy-to-use fault isolation tools;
z
G.992.1 interface standard and auto-sensing.
