In Section 3: Line Interface and Section 3.1: Functional Description, corrected dB values
for E1 and T1 (page 10 and page 13):
Added Note 1 (GBD for cold temp) to Absolute Maximum Ratings (Section 36).
Replaced Figure 24-3 and Figure 24-4, added Table 24-A and Table 24-B.
Added lead-free packages to Ordering Information table on page 1.
Add revision history table: The previous version of the DS2155 data sheet (12-06-02) did
not incorporate a revision history table and did not describe new features added to B1
revision of the DS2155.
