V5-PSTN Service
ZXMSG 5200 supports analog subscriber's access and subscriber
side switches. The subscriber signaling is Dual Tone Multi-
Frequency (DTMF) signals or line status signals. ZXMSG 5200
supports direct subscriber access (when a subscriber switch is
used), thus posing no special restriction on the supplementary
services.

V5-ISDN Service
ZXMSG 5200 provides ISDN service through V5 interface. It has
restrictions neither on bearer and supplementary services of B
channel nor packet and supplementary services of D channel. In
case where the ZXMSG 5200 convergence service is not adopted,
a V5 interface is used between a switch and ZXMSG 5200 to
access the ISDN subscribers directly to the switch.
Figure 10 shows the flow of ISDN service though V5 interface.
