Panasonic KXUDS124 Operating Guide

In order to be able to move between coverage areas during a call (Handover), synchronisation between

SIP-CSs is necessary. If synchronisation between SIP-CSs has not been configured, handover will fail. The

source of synchronisation is called a Master CS and the target of synchronisation is called a Slave CS. An Air

Sync Group is created with the Master/Slave CSs on different levels. The source of synchronisation for each

SIP-CS in an Air Sync Group is called an Air Synchronisation Master CS.

The number of Master/Slave levels in an Air Sync Group cannot exceed 8. To ensure that the number of levels

does not exceed 8, locate the Air Synchronisation Master CS in the centre of the group. A greater number of

levels can lead to instability in handover and air synchronisation.

The Master CS of Air Sync Group 1 is called the Super Master CS and controls the whole system.

The Master CS is located in the centre of the installation site for each Air Sync Group.

The Master CS is 

NOT located in the centre of the installation site for each Air Sync Group. Therefore, the

number of layers in the hierarchy exceeds 8.

Choosing the best site for the SIP-CS requires careful planning and testing. The best location may not

always be convenient for installation.

•

It is necessary to locate SIP-CSs within synchronisation range of other SIP-CSs, however, locating

SIP-CSs too close to each other can lead to interference and a reduction in the number of simultaneous

calls. In a regular office, the average distance between SIP-CSs should be approximately 30 m.

Upute za postavljanje

Da biste se mogli kretati između područja pokrivanja tijekom poziva (prebacivanje), potrebno je sinkronizirati 

SIP-BS-ove. Ako sinkronizacija između SIP-BS-ova nije konfigurirana, prebacivanje neće biti moguće. 

Izvor sinkronizacije naziva se nadređeni BS, a cilj sinkronizacije podređeni BS. Grupu za bež. sinkr. čine 

nadređeni/podređeni BS-ovi na različitim razinama. Izvor sinkronizacije za svaki SIP-BS u grupi za bež. 

sinkr. naziva se nadređeni BS za bež. sinkr.

Maksimalan broj nadređenih/podređenih razina u grupi za bež. sinkr. je 8. Da broj razina ne bi prešao 8, 

postavite nadređeni BS za bež. sinkr. u središte grupe. Velik broj razina može dovesti do nestabilnosti u 

prebacivanju i bežičnoj sinkronizaciji.

Nadređeni BS grupe za bež. sinkr. 1 naziva se centralni nadređeni BS i upravlja cijelim sustavom. 

Nadređeni BS postavljen je u središte svake grupe za bež. sinkr.

Broj nadređenih/podređenih razina: 5 

Nadređeni BS 

NIJE postavljen u središte svake grupe za bež. sinkr. Stoga broj razina u hijerarhiji prelazi 8.

Broj nadređenih/podređenih razina: 9 

•   Odabiru najboljeg mjesta za SIP-BS mora prethoditi pažljivo planiranje i testiranje. Najbolja lokacija 

neće uvijek biti prikladna za postavljanje.

•   Potrebno je postaviti SIP-BS-ove unutar sinkronizacijskog raspona drugih SIP-BS-ova, međutim, 

premali razmak između SIP-BS-ova može dovesti do smetnji i smanjenja broja istovremenih poziva. 

U uobičajenom uredu prosječna udaljenost između SIP-BS-ova trebala bi iznositi približno 30 m.
