I found cause of this problem:
Than you use 'ppp reliable-link' you must use compression 'compress predictor'. But in documentation you can read:
Although LAPB protocol overhead consumes some bandwidth, you can offset that consumption by the use of PPP compression over the reliable link. PPP compression is separately configurable and is not required for use of a reliable link.
