Frame Relay Routers are capable
of establishing PPP-MP links
over Frame Relay. The LR1530A-
R3 model sends compressed data
up to 128 kbps and uncompressed
data up to 56 kbps. The LR1531A-
R2’s internal CSU/DSU handles
data at speeds up to 56 kbps while
10BASE-T communications run at
10 Mbps. The LR1535A-R2’s built-
in CSU/DSU enables data commu-
nications at T1 speeds of 1.544
Mbps or E1 speeds of 2.048 Mbps.
