*(See the note on the previous page.) Only the most popular of the speeds that SMEs with the 6.144-MHz
customization can reach are listed here. These modified SMEs are capable of any data rate up to 1.536 Mbps
that evenly divides 3.072 Mbps. That is, if you don’t get a remainder when you divide 3,072,000 bps by your
desired speed, these SMEs can be set to that speed. Call us for technical support if your desired data rate
isn’t shown here.
