There comes up the problem of interference In V 21 V 22 V 22bis operating modes the T 336Cx used the frequency split method Whereas in V 32 V32bis V 34 mode it must provides echo cancellation because originate and answer modems occupy the same frequency band 4W leased line offers two independently unilateral transmission channel therefore it can achieve full duplex communication with less interference Obviously the line quality of 4W leased line is better than that of 2W leased line However the T 336Cx does an excellent job with both 2W and 4W leased lines and even dial line MODEM _ __ MODEM 2W Leased Line MODEM A MODEM 4W Leased Line FIG 4 3 2W 4W leased line 4 4 Answer Mode VS Originate Mode While using the dial line there must be a modem initiating the call once the exchange recognizes the number it connects the circuit to the answering modem with ring signals Answering modem can pick up the call manually or automatically Afterward it issues the answer tone to connect with the originate modem Usually we call the modem which dials the call as originate mode and the other one as answer mode According to the role of the connection the training sequence and working frequency band of either modem is different from each other even operating with leased line With 2 4 wire full duplex operation such as V 21 V 22 V 22bis V 23 V 32 V 32bis V 34 Bell 103 and Bell 212A there should be an originat

Leased Line There are two kinds of telephone lines dial lines and leased lines described as below A Leased line provides users a dedicated communication channel Both ends of the circuit are permanent It offers continuous service and provides absolute security It will not be invaded by any other circuit due to the dedication 1t supports better quality and higher reliability DTE MODEM 7 MODEM DTE FIG 4 1 Leased Line B B Before using a dial line such as the circuits for telephone and facsimile machine we have to dial a number For the users who are used to communicate with different counterparts such as bulletin board system BBS public service network and toll free services this will be a better choice Due to the time consuming dialing procedure 45 60 Sec the efficiency is lower than that of leased lines It is even worse when line or destination is busy Furthermore the communication path is different at each dial so the line quality is not ensured Besides it doesn t guarantee good security To make this modem operate in 2 4 wire leased line or dial line you need to do some settings with Line Type Selection under LINE SETUP menu FIG 4 2 Dial Line 38 CHAPTER 4 GENERAL INFORMATION AND FEATURES 4 3 2W 4W Leased Line We had talked modem operate in the previous section There are two wire leased lined and four wire leased line 2W leased line achieves full duplex with only a pair of lines
