DIP Switch Settings for 6X50 and 6X85 DS1 Cards
(NTP 297-8991-505 & NTP 297-YYYY-847)
The following equalization/build-out DIP switch settings are for 6X50AA
& AB DS1 packs located in the DTC/LGC frames, and 6X85AA & AB
DS1 packs located in the SMS/SMU/SMS-R frames. It is important that
the DIP switch settings are set properly to prevent SLIPs on the P-side of
the carrier system. This can cause customer complaints about problems
with FAXing and errors with data transmission, as well as noise if the slips
are excessive.
Note: It is important to know the card type (AA, AB etc.), release number
on the card, and gauge and length of the DS1 cable from the equip-
ment bay (DTC/LGC etc.) to DSX bay before making any settings.
Note:
S1& S2 or S320 & S620 are banks of DIP switches for the even and
odd links/ports and are different depending upon the card type.
Note: NTMX81 DS1 Interface Card DIP Switch Settings and the Star
Hub Backplane DIP Switch Settings can be found with the Star
Remote within this QRG.
Note: EMI = Electromagnetic Interference Protection
