Dte Data Connection/Primary Dte - ADTRAN DSU III ARdc Manual

DTE DATA CONNECTION/PRIMARY DTE

The primary DTE should be connected to either the EIA-232 DTE connec-
tor or the CCITT V.35 DTE connector. The maximum cable lengths recom-
mended are 50 feet for the EIA-232, and 100 feet for the CCITT V.35. The
pin assignments for the connectors are listed in Table 2-2 on page 2-4 and
Table 2-3 on page 2-5.
The V.35 connector is recommended for use with data rates above
19.2 kbps. The EIA-232 connector works up to 56 kbps with a low capaci-
tance cable or with the external transmit clock option selected. The DTE
rate is configured from the front panel. The DTE can operate in asynchro-
nous or synchronous modes.
To prevent possible radio frequency interference emissions, a
shielded cable is required.
