Console Port cable installation procedure is as follows:
Step 1: Choose a terminal (a PC for example).
Step 2: Turn off the power of the terminal, and then use the RS232 cable to connect the GT48 Console Port to
the terminal.
4.6.2 Connecting
Ethernet
Port
There are three 10/100 BaseT Ethernet ports with RJ45 connector type on a GT48. Each Ethernet port is
equipped with LED status display. Ethernet port transmits voice packet as well as management, maintenance
and control information.
The Ethernet Cable needs to be carefully made to ensure IP data and voice quality. The following is the
Ethernet cable making scheme:
Step 1: A user can use a proper cable peeling cutter to peel away 3cm skin of a CAT-5 cable. What is left is
shown in Figure 4-2.
Figure 4 - 2
Step 2: Twisted pairs. Currently the most commonly used standard wiring scheme is EIA/TIA T568B shown in
Figure 4-3. In the wiring scheme, pin 1 and 2 are a pair, pin 3 and 6 are a pair, pin 4 and 5 are a pair and
pin 7 and 8 are a pair. According to the Fig. 4-3, twisted pairs line up with colors (1: white orange
，
2:
orange
，
3: white green
，
4:blue
，
5: white blue
，
6:green
，
7: white brown
，
8: brown). Please pay special
attention that the green and white green are separated by a pair of blue wires. It is a common mistake to
put green and white green close together, which will result in interference and therefore lower
transmission efficiency.
