Hi, everyone. Nicole here again.. with another question..
in our business, for security reasons, we have always, recorded all of the phone conversations with all of our clients, for quality purpose. we have always used, the linksys PAP2 and use different Voip companies, like vonage,Phone Power, Vocalocity, and others. To record all of incoming and outgoing conversation in the business.
When we use any of our 5 modem routers, with the PAP2, and use any of 5 Voip providers, the calls get recorded, in Full Duplex mode. and gives us a green light. witch means, the person who is calling, and the person who is receiving the call, are both being recorded, and there is no problem.
But when i connect the DGL 4500, the calls get recorded in Half Duplex mode, and gives us a red light, wich mean, that only one of the persons voice, is being recorded.
P.S
So, besides Voip, we made another test, about Online Gaming, and other things. We tested Call Of Duty, black ops, and Gears OF war 3 Beta. for roughly 5 hours. We had 5 of the most skilled people, play for 1 hour online, in both COD-Black OPs and Gears Of Wars 3 beta. and these are the results.
D-LINK MODEM + D-LINK DGL 4500 ROUTER 2 WIRE 2700HG MODEM ROUTER
Call OF Duty Black Ops
Player 1 Player 1
17 kills 8 deaths 26 kills 4 deaths
Player 2 player 2
19 kills 6 deaths 28 kills 4 deaths
player 3 player 3
14 kills 6 deaths 23 kills 2 deaths
player 4 player 4
12 kills 5 deaths 27 kills 3 deaths
player 5 player 5
14 kills 7 deaths 22 kills 3 deaths
Gears OF wars 3 Beta
Player 1 player 1
12 kills 8 deaths 19 kills 2 deaths
player 2 player 2
10 kills 6 deaths 17 kills 2 deaths
player 3 player 3
10 kills 4 deaths 22 kills 1 deaths
player 4 player 4
9 kills 6 deaths 26 kills o deaths
player 5 player 5
12 kills 5 deaths 21 kills 3 deaths
These calculation, where made from 5 hour of gameplay, in diffrent maps, with each player.
now this is what the player's say, with the DGL 4500, people who played gears of war 3, would say, that with the DGL 4500, you cannot see the lag, but, when trying to battle someone, close with the shotgun, or with the sawed off. they would most likely, kill someone 60%, but when they used the 2 WIRE 2700 HG , they felt more, free ness, and quickness. witch meas, that they kill someone 95% of the time.
same thing with call of duty, when trying to knife someone or kill someone with the shotgun. or when shooting, someone from far distance , people when using the DGL 4500 , would only get about 65% of the time, with the 2 WIRE 2700HG, they would get about 90% of the time that kill.
These are players, last from 8am till 12 midnight at night time, playing in my gaming lounge. practicing for international tournaments.
P.S.S
I don't know if it has something to do with the settings, on the DGL 4500 WAN, or LAN port Settings or Configuration , or what settings, im supposed have on or off, or have checked, or not..? or it if has something to do, with the D-link Modem 2320B, being connected into the DLINK DGL 4500 ROUTER. i think its something to do with the settings in the DLG 4500. i just don't know.
hope someone can help me on this one. because we have setup, all of our gaming lounge, with the D-LINK 2320B modem, + DGL 4500 Router. Internet speeds are 50MB Download, 2MB upload. there must be a way around this.
The Point to this, is. If there is a way to get FULL DUPLEX working on DGL 4500. this problem will be solved. for both, VOIP and Online gaming.
Important NoticePeople, will never notice this, unless they have at least 5 different modems, or different router, like we have. we tested all of them. and they work fine. only problem is with the DGL 4500. Also tested my other DGL 4500 and same things happens.
we use, different voip licensed programs to record our calls like MiaRec Business and other that cost $300.00 per phone line. , also if you don't have a licensed voip program like we have, a quick way, to test this for free. is with the oxid.it Cain & Abel program its free.and one of our players, even tested, with this app. and it only works in Half Duplex Mode.
the PAP2 Linksys VOIP adapater is connected to one of the LAN ports on the DGL 4500, and then , all recording loggs, gets saved, in a laptop that is connected, via Wireless.
im using Firmware Version : 1.15, 2008/10/29
thank you and god bless everyone
--------this is something useful i found---------
Half-duplex Ethernet is defined in the original 802.3 Ethernet; Cisco says it uses only one wire pair with a digital signal running in both directions on the wire. Certainly, the IEEE specifications discuss the process of half duplex somewhat differently, but what Cisco is talking about is a general sense of what is happening here with Ethernet.
It also uses the CSMA/CD protocol to help prevent collisions and to permit retransmitting if a collision does occur. If a hub is attached to a switch, it must operate in half-duplex mode because the end stations must be able to detect collisions. Half-duplex Ethernet typically 10BaseT is only about 30 to 40 percent efficient as Cisco sees it, because a large 10BaseT network will usually only give you 3 to 4Mbps at most.
But full-duplex Ethernet uses two pairs of wires, instead of one wire pair like half duplex. And full duplex uses a point-to-point connection between the transmitter of the transmitting device and the receiver of the receiving device. This means that with full-duplex data transfer, you get a faster data transfer compared to half duplex. And because the transmitted data is sent on a different set of wires than the received data, no collisions will occur.
The reason you don’t need to worry about collisions is because now it’s like a freeway with multiple lanes instead of the single-lane road provided by half duplex.
Full-duplex Ethernet is supposed to offer 100 percent efficiency in both directions e.g., you can get 20Mbps with a 10Mbps Ethernet running full duplex, or 200Mbps for Fast Ethernet. But this rate is something known as an aggregate rate, which translates as You’re supposed to get 100 percent efficiency. No guarantees, in networking as in life.
Full-duplex Ethernet can be used in three situations:
- With a connection from a switch to a host
- With a connection from a switch to a switch
- With a connection from a host to a host using a crossover cable
Now, if it’s capable of all that speed, why wouldn’t it deliver? Well, when a full-duplex Ethernet port is powered on, it first connects to the remote end, and then negotiates with the other end of the Fast Ethernet link. This is called an auto-detect mechanism.
This mechanism first decides on the exchange capability, which means it checks to see if it can run at 10 or 100Mbps. It then checks to see if it can run full duplex, and if it can’t, it will run half duplex.
