2) Point-to-point fractional E1 mode in “Terminal clock — Slave clock” structure

When remote DTE equipment has to follow the clock phase of local DTE equipment, which is to

say, TX CLOCK of local DTE is internal clock source, users can set Terminal Clock Mode in local

converter, and Slave Clock Mode in remote converter, and must configure clock frequency at V.35

interface of local DTE equipment.

When using “Terminal clock — Slave clock” connection structure, if DXC and MUX devices are

connected in series in E1 link, then DXC, MUX and remote converter should be at Slave Clock

Mode (following E1 link clock).

3) Point-to-point fractional E1 mode in “Slave clock — Slave clock” structure

When using Slave Clock Mode at both sides, it is required to ensure that the clock source is

provided by DXC, MUX or other PCM fractional E1 equipment in the E1 link, and there is only

one clock source in the E1 link.
