Series. The module provides up to 2.048 Mbps on each network interface. See Table A-7 on page 87 for the
pinouts. See Table A-15 on page 91 for the DBU connector pinouts. An optional DIM is required for dial
backup applications.

(1200865L1), and ISDN S/T (1200875L1) DIMs for dial backup applications. The
1202872L1 Dual T1 module supports only the analog modem (1200864L1) DIM for dial
backup applications.
