•E1, 2.048 MHz, 64 KHz—Choose E1,2.048 MHz, or 64 KHz depending on the signal supported
in your market. For example, 64 KHz is used in Japan. E1, 2.048 MHz, and 64 KHz are physical
signal modes used to transmit the external clock (from a GPS for example) to BITS.
•BITS In State—Set BITS-1 and BITS-2 to OOS.
•BITS Out State—Set BITS-1 and BITS-2 to OOS.
•Coding—Not relevant for internal timing; the default (HDB3) is sufficient.
•Framing—Not relevant for internal timing; the default (FAS + CAS + CRC) is sufficient.
•Sync Messaging—The box is checked automatically.SSM is used to deliver clock quality. The SSM
supported in SDH is G811, STU, G812T, G812L, SETS, DUS (ordered from high quality to low
quality). If you selected 2.048 MHz or 64 KHz, the SSM option is disabled.
•AIS Threshold—Not relevant for internal timing.
•LBO—Not applicable for internal timing.
•Sa bit—Not applicable for internal timing.
