| Q2: |
How do I test the MTD803 chip? |
| A2: |
Myson Century provides a new manufacture test program tool for the MTD803 chip. It¡¦s used to test the transmit/receive functions of the MTD803 adapter. Of course, OEM customers can use it for mass-production test. It includes four files:
MTDPKT.COM
MTEST.EXE
MTD803.INI
README.TXT
You also need to refer to the README file to get more experience in how to setup and test the MTD803A chip.

| Q3: |
How do I configure the EEPROM of MTD803? |
| A3: |
Myson Century provides a new on-line programming tool for configuring the EEPROM of MTD803A. It includes three files:
EEPROM.EXE
EEPROM.DAT
README.TXT
You also need to refer to the README file for more information on how to configure the EEPROM.

| Q5: |
What is a CRC/Alignment error? |
| A5: |
When a station sends a frame, it appends a CRC(Cyclical Redundancy Check) to the end of the frame. This CRC is generated from an algorithm and is derived from the data in the frame. If the frame is altered between the source and destination, the receiving station will recognize that the CRC does not match the actual contents of the packet. All frames should end on an 8-bit boundary, but problems on the network could cause the number of bits to deviate from the multiple of 8. Both CRC errors and alignment errors are grouped together as the single CRC/Alignment error counter. |

| Q6: |
What is jabber? |
| A6: |
Jabber is described most often as a frame greater than the maximum of 1518 bytes with a bad CRC. A jabbering NIC is often indicative of a hardware problem with a NIC or transceiver. |

| Q7: |
What is jam? |
| A7: |
When a collision is recognized by a transmitting station, a bit sequence called jam is transmitted. This jam is 32 bits long, which is long enough to traverse the entire collision domain so that all transmitting stations can detect the collision. |

| Q8: |
What is a MAC address? |
| A8: |
It is the unique hexadecimal serial number assigned to each Ethernet network device to identify it on the network. With Ethernet devices (as with most other network types), this address is permanently set at the time of manufacturer, though it can usually be changed through software. |
| Top |
| Q9: |
Why must the MAC address to be unique? |
| A9: |
Each card has a unique MAC address, so that it will be able to exclusively grab packets off the wire meant for it. If MAC addresses are not unique, there is no way to distinguish between two stations. Devices on the network watch network traffic and look for their own MAC address in each packet to determine whether they should decode it or not. Special circumstances exist for broadcasting to every device. |

| Q10: |
What is NDIS, packet driver, ODI.? |
| A10: |
NDIS is a Microsoft/3com puppy that allows "stacking" of multiple protocols for a single underlying driver. Essentially it allows a single Ethernet card in a PC(it's not limited to Ethernet) to speak many different network "languages", and usually at the same time.
Packet driver is another method of allowing multiple protocols to access the network interface at the same time. Developed and supported by FTP Software Inc, Clarkson University, BYU and, more recently, Crynwr Software, the packet driver spec (PDS) is used to provide a device independent interface to various TCP/IP applications, and often in combination with concurrent Novell access (IPX/SPX).
ODI is Novell and Apple's equivalent of NDIS. There are differences between the two specs, but not so much as to warrant description in this text. The next logical question is "which one should I use?" There is no simple or obvious answer, except that you should use the one most commonly required by your software.

| Q12: |
How long does the MTD981AF take from unlocking reset stage to starting to transmit the data again? |
| A12: |
After power on reset, the MTD981AF normally needs to wait until the PLL (Phase Lock Loop) circuit becomes stable (about 1 ms). Then it can start to transmit data. |
| Top |
| Q13: |
How long does the MTD981AF take from unlocking reset stage to turning LINK on? |
| A13: |
In force 10 MHz condition, it needs 150 +/- 50 ms to turn the LINK on. In force 100 MHz condition, it needs 1ms to turn the LINK on. In auto negotiation condition, additional 1500ms are needed for both of the first two conditions. These timing is described in the IEEE802.3 specification. |

| Q14: |
What does the MTD502EF MAC address learning table do? |
| A14: |
The MTD502EF uses dynamic addressing learning algorithm to learn the MAC address. The MTD502EF searches for the Source Address (SA) of an incoming packet in the address table. If the SA is not found in the table , the MTD502EF waits until the end of the packet and updates the address table. If The SA is found in the table, the MTD502EF will reset the aging time of the SA. |

| Q15: |
What happens if backpressure disable is set, both ports are configured to half and there is no empty buffer in the MTD502EF? |
| A15: |
In half duplex mode, the MTD502EF provides a backpressure control mechanism to avoid dropping packets during network conjoint situation. When the " backpressure control enable " bit is set during power on reset, it enables the MTD502EF to support backpressure function in half duplex mode. When the output port buffer queue's on using value reaches the initial setting threshold value, the MTD502EF will send a JAM pattern in the input port when it senses an incoming packet, thus forcing a collision to inform the remote node transmission to back off effectively avoiding dropping packets. If the "back pressure control disable" bit is set, and there is no free buffer queue available for the incoming packets, the incoming packets will be dropped. |
