Connection

When you click Connection, the Connection Conﬁguration page appears. This screen’s appearance will vary

depending on your type of connection to the Internet.

Here is an example.

Here you can set up or change the way you connect to your ISP. You should only change these settings at your

ISP's direction, or by agreement with your ISP.

◆ DSL Auto Modulation: provides automatic rate adaptation which tries to sync at the fastest possible modula-

tion.

◆ DSL Transport: Select ATM (Asynchronous Transfer Mode), PTM (Packet Transfer Mode), AUTO, or NONE

from the pull-down menu. These modes depend on the equipment used by your ISP. Many providers now sup-

port dual mode IP DSLAM line cards that default to PTM, with ATM as a fallback. The default AUTO allows the

best compatibility.

◆ Auto Detection VPI/VCI: If this checkbox is checked, your Gateway will attempt to detect the virtual circuit

pairs in use by trying the most common ones in succession until one is found. Thereafter, the Gateway will

always attempt to use that pair. If it cannot detect the VPI/VCI set in use, you can uncheck the checkbox, and

enter the values manually.

◆ VPI/VCI: These values depend on the way your ISP's equipment is configured. 0/35 and 8/35 are the most

common virtual circuit pairs, but others are also used.

◆ Encapsulation: The authentication and encapsulation protocol is determined by your ISP by the type of

account that you have signed up for and the model of your Motorola device. Choose from the pull-down menu:

pppoe-llc, pppoe-vcmux, ether-llc, ip-llc, pppoa-llc, or pppoa-vcmux

◆ Bridging: Your Gateway can be turned into a simple bridge, if desired. Select Enabled from the pull-down

menu. However, it will no longer provide routing or security features in this mode.

◆ Use Static IP Addressing: Your service provider may tell you that the WAN IP Address for your Gateway is

static. In this case, check the checkbox.
