2.3.12.6 RSGM Service Attributes -PGM Code 435-

When connected over an unmanaged network (internet), an RSGM communicates with the iPECS
resources and other users by way of a VoIP channel.
channels in most MFIMs, refer to Table 1.1-1, which are intended for use over a managed network
(LAN/WAN). The VOIM (Voice over IP Module) provides additional channels that are intended for
use over an unmanaged network. VOIM channels support IPSec and adjustable DiffServ pretag.
The IP channels are assigned to a CO/IP line group, refer to CO/IP Attributes in
The MFIM and VOIM VoIP channels should be assigned to different CO/IP line groups. This entry
then determines which CO/IP Line group will be used for communication with the RSGM. To
assure that IPSec support is provided, the RSGM should be assigned to use a group with IP
channels only from a VOIM.
The IP header TOS byte is employed to define a Differentiated Services Code Point (DSCP),
which is used by routers to prioritize packets. Most routers will prioritize packets with higher
DiffServ Code Points. However, should delays through the router become significant, high priority
DSCP packets are the first discarded. Under high packet loss, decreasing a high DSCP, may in
fact improve performance.
The RSGM local PSTN line, if equipped, is assigned as the user's Private Line. The user may
access this Line automatically when dialing "9", or may access a CO/IP channel from the first
CO/IP Group as defined in
