[Sls-slp] USLP Section 2.4 Restrictions on Services

[Gian.Paolo.Calzolari at esa.int]

Greg,
        At glance and in general it may be reasonable to avoid mixing 
services on the same channel.
This would call for applicability also to USLP unless you are sure that in 
USLP services can be mixed on a Channel without getting into troubles 
(e.g. because the type of service provided by the data unit is signalled 
within the frame).
Regards

Gian Paolo

Dear SLP WG,

There is an open question concerning Section 2.4 Restrictions on Services 
within the USLP White Book specification.

Do these restrictions below still apply to USLP ? What is the motivation 
for them ? If we cannot generate valid reasons for keeping them, I 
recommend we remove them. Please comment.

Best regards,
Greg

2.2.4     Restrictions on Services
There are some restrictions on the services provided on a Physical 
Channel, as follows:
a)     On one Physical Channel, the Insert service shall not exist 
simultaneously with the Virtual Channel Frame or Master Channel Frame 
service.
b)    If the Master Channel Frame Service exists on a Master Channel, 
other services shall not exist simultaneously on that Master Channel.
c)     If the Virtual Channel Frame Service exists on a Virtual Channel, 
other services shall not exist simultaneously on that Virtual Channel.
d)    If the Virtual Channel Octet Stream Service exists on a Virtual 
Channel, other services shall not exist on that Virtual Channel.
e)     On one MAP Channel, the MAP Access Service shall not exist 
simultaneously with the MAP Packet Service.
