In a NetWare 4 environment, WAN traffic can be seen from the following sources :

1. Time synchronisation.
2. NDS.
3. SAP/RIP.

Traffic from each of these sources MAY be reduced in the following ways. 

Time Synchronisation : The following two SET parameters may be adjusted to change the frequency (number) and polling interval (SECONDS) for time synchronisation polling :

• TIMESYNC Polling Count = number (DEFAULT 3) (Decrease this figure) 
• TIMESYNC Polling Interval = seconds (default 600) (Increase this figure) 

NDS : NDS traffic may be reduced by using the DS Filter program,which allows setting of the periods during which synchronisation may take place. Using this program, NDS synchronisation will only occur at certain times of the day. DS Filter NLMs are available as part of the Novell Multi Protocol Router (MPR) 3.0 product, or on the Novell Consulting Toolkit.

Additionally, it is possible to change the SET parameter : NDS inactivity synchronization interval = minutes (default 30) to increase the time between periods when a synchronisation attempt takes place, if no other activity has been seen during this time. This is of particular interest on ISDN (and other switched) connections where frequent activation of the line might be undesirable. 

SAP/RIP :  SAP (Service Advertising Protocol) and RIP (Routing INFORMATION Protocol) traffic may be reduced by the use of a filtering program included with NetWare 4.0x and 4.1. This program can be used on servers which are acting as routers WITHIN the network.If servers are not acting as routers, it is suggested that the filtering facilities as provided by the third-party router are used instead.

Components Of Modem :

1. PC Interface : It is interface between PC & MODULATOR circuit, which connects PC & modem together. It trans signals from PC to Modem & vice versa. It also performs CONVERSION of data from ANALOG to digital & vice versa.
2. Modulator Demodulator Circuit : It performs modulation of signals. Mainly it is based on frequency modulation in order to achieve max trans rate.
3. Line Interface : It is interface between modulation circuit & telephone line. It connects telephone with modem with the help of twisted pair CABLES. It transmits modulated signals over telephone lines.

Components Of Modem :

Modulation :- It is a process with which original SIGNAL is transmitted over a carrier wave with the fixed amplitude or frequency. Carrier wave is a signal, which is used for trans of audio or video. Mainly these signals are trans over telephone lines. Two basic operations are performed by the Modem :

1. Conversion of data from digital to analog form
2. Conversion of data from analog to digital form

Modulation is classified into :

1. Amplitude : In this technique, amplitude of the carrier wave is constant from SOURCE to destination to avoid attenuation of a signal. Amplitude is voltage between 2 consecutive peaks. It is peak-to-peak voltage.
2. Frequency : In this, frequency of the carrier wave is constant from source to destination in order to maintain speed of trans. It is no of cycles PER second. It is calculated in TERMS of wavelength (LAMDA). Wavelength is the distance between 2 consecutive peaks. Frequency & wavelength are inversely promotional to wavelength.
3. Phase modulation : In this technique amplitude as well as frequency of carrier wave is constant from source to destination. Phase Modulation is also called as Shift Key.

1. Reboot the system from A drive. Min DOS version MUST be COMPATIBLE with Netware with this command.com is loaded by w/s.
2. INSERT w/s installation disk in drive & type A:> IPX.COM. When IPX is loaded it will configure address for the w/s.
3. Type A:>NETX.COM with which latest version of Netware is loaded by w/s with the server if version at Netware w/s matches with the server it displays F prompt.

Dedicated Workstation :

These are diskless w/s, which are totally DEPENDANT on server for booting process. Procedure :

1. Insert Boot ROM Chip into the NIC of w/s.
2. Switch on w/s with this NET$DOS.SYS file gets executed from w/s. It also called as Netware Shell. It acts as interface between DOS & Netware. NOTHING but it intersects DOS with Netware. Whenever commands are related with DOS then these commands are executed from w/s & if commands are related with Netware, it executed under Netware Environment. This file is basically used to distinguish between DOS & Netware e.g. Setpass executed from w/s & Attached directed to the Server.
