Configuring Synchronous Services
This chapter describes how to edit line services for synchronous WAN circuits and
the Link Access Procedure Balanced (LAPB) protocol. It contains the following
sections:
Overview of Synchronous Services
Each synchronous interface:
• Connects a Bay Networks router or switch to data communications equipment
(DCE) devices, such as DSUs, CSUs, and modems.
• Supports a range of physical connections, including V.35, X.21, RS-232, and
RS-449/422 balanced.
• Supports both leased and dial-up circuits. See Configuring Dial Services for
information about configuring dial-up circuits.
• Supports many WAN software services, including PPP, X.25, frame relay,
SMDS, HDLC encapsulation, and ATM DXI.
• Operates from 1200 b/s to a maximum of 2.048 Mb/s, full duplex.
