9-4 Administration Guide
For example, for the ATM-based DSLAM mode Nokia Fixed, the following screen displays.
■ For all except the (HDLC) Copper Mountain Operation Mode, the Data Rate Mode pop-up menu offers the
choice of Hunt or Locked mode.
■ If you select Hunt (the default) the device will attempt to connect at the data rate you specify in the
Data Rate selection, but if it cannot do so, it will then hunt through all the available data rates until it
finds one at which it can establish a connection. When it does establish a connection, it will store that
data rate and use it the next time you connect.
■ If you select Locked, the device will always attempt to connect at the data rate you select in the next
step.
■ The Data Rate pop-up menu allows you to set the initial or locked data rate for the SDSL link (and the
attached CPE device). The pop-up menu offers you a choice of connection speeds that vary depending on
the rates that your selected DSLAM supports.
■ The Display/Change Circuit, Add Circuit, Delete Circuit menus permit you to assign multiple permanent
virtual circuits. For detailed information on multiple PVCs, see “Multiple ATM Permanent Virtual Circuit
Support” on page 9-5.
■ Select Data Link Encapsulation and press Return. The pop-up menu will offer you the choice of PPP or
RFC1483. The HDLC (Copper Mountain) Operation Mode also offers Frame Relay. Your selection depends
on which type your ISP uses.
■ If you selected PPP as your data link encapsulation method, the PPP Mode pop-up menu offers the
choice of VC Multiplexed (the default) or LLC SNAP.
■ If you selected RFC1483 your data link encapsulation method, two additional options display: an
RFC1483 Mode pop-up menu offers the choice of Bridged 1483 or Routed 1483. Bridged 1483 per-
mits use of PPP over Ethernet (PPPoE) and is the default. You can then toggle PPPoE On or Off.
Choosing Routed 1483 hides the PPPoE option.
