1.2 Replacing a Multiplexer Level 1 to Level 3 (M13) with an ATM System
In a second public network application, an M13 is replaced with an ATM system containing an
AAL1gator II. M13s are often used to provide DS1 services. As Figure 5 shows, these DS1 cir-
cuits must be emulated by an ATM DACS or an ATM M13 when the backbone is converted to
ATM.
