Configuring T1 FrameLine Cards
(MAX TNT, DSLTNT)
Introduction to T1 FrameLine
The T1 FrameLine slot card provides 10 unchannelized T1 lines, each of which can be used for
one nailed connection. Associated with each T1 line is a Serial Communications Adapter
(SCA), which is responsible for receiving and transmitting HDLC frames. Because there is
only one SCA per line, only one PPP or Frame Relay link (possibly with multiple DLCIs) can
be active per line.
Unlike other slot cards, such as the Series56 II and Series56 III Digital Modems cards or
Hybrid Access (HDLC) cards, call routing profiles are not used for the FrameLine card and are
ignored if they exist. The data pathway is directed to an on-board SCA device and cannot be
routed to another host card. All packetization of data occurs locally.
Overview of supported features
This section describes the T1 FrameLine slot card’s support for the following protocols:
• PPP
• Frame Relay
• Routing protocols
• SNMP
PPP
The T1 FrameLine slot card supports PPP as follows:
• Only one PPP session per line.
• Bandwidth per session is 1-24 DS0 channels.
• Channels need not be contiguous.
