### Description

```asn1
sysServices OBJECT-TYPE
SYNTAX INTEGER(0..127)
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A value which indicates the set of services that this entity primarily offers.
The value is a sum. This sum initially takes the value zero, Then, for each
layer, L, in the range 1 through 7, that this node performs transactions
for, 2 raised to (L - 1) is added to the sum. For example, a node which
performs primarily routing functions would have a value of 4 (2^(3-1)).
In contrast, a node which is a host offering application services would
have a value of 72 (2^(4-1) + 2^(7-1)). Note that in the context of the
Internet suite of protocols, values should be calculated accordingly:
layer functionality
1 physical (e.g., repeaters)
2 datalink/subnetwork (e.g., bridges)
3 internet (e.g., IP gateways)
4 end-to-end (e.g., IP hosts)
7 applications (e.g., mail relays)
For systems including OSI protocols, layers 5 and 6 may also be counted."
