ZhoneGR303-MIB Table View

The GR-303 Interface Group Table.
          
Minimum granularity for GR-303 provisioning is the 
Interface Group (IG) abstraction aka Internal Group. 
The Interface Group Table describes attributes for 
each provisioned GR-303 Interface Group and is also 
the base table for the augmenting Interface Group 
Control Channel Table.  Each IG is configured 
manually by an administrator.
          
Each IG entry (row) is indexed by a unique IG name.
Where both active and standby Interface Groups exist,
the same IG name refers to both the active and standby 
Interface Group.
          
For all IG entries, the (shelf, slot) is unique. The 
IG name is an externally visible global name that
refers to both the active and standby IGs. IG names 
are used for call routing and does not change during 
the IG lifetime.
          
The maximum number of entries or Interface Groups
is 'system-wide' and not bounded by a slot or card,
but can span multiple cards and shelves.
          
Each Interface Group is associated with the following
tables: 
* augmenting Interface Group Control Channel row
* DS1 Line Mapping Table
* Line Circuit CRV Table
* augmenting IG Statistics Current row
* IG Statistics Interval Table
* augmenting IG Statistics Total row
          
After creating an IG entry an associated primary DS1 
must be created. Without the primary DS1 an SNMP-SET 
operation is not allowed on any 303 tables except the 
deletion of the IG entry.

interfaceGroupEntry row .1.3.6.1.4.1.5504.4.3.1.1.1

An entry in the interfaceGroupTable. Indexed
by igNameId. Interface Groups can span multiple
cards and shelves. A row in this table is
created by setting the value of igRowStatus
to 'CreateAndGo', and setting the …

The GR-303 DS1 Line Mapping Table.
          
The DS1 Line Mapping Table describes attributes 
for DS1 Line Termination and the mapping between 
the Interface Group and DS1 standard MIB (rfc2495).
          
The maximum number of entries is determined by 
the maximum number of DS1 lines for the Interface
Group, which is 28.  Each Interface Group is 
associated with a ds1LineMapping Table indexed 
by (IG name, line group ID, ds1 channel number), 
where line group ID is either a physical T1 line 
group ID (eg, Dibrizzi) or a channelized DS3.  
DS1 channel number is one of 28 DS1s associated 
with a channelized DS3, that is being provisioned 
to the Interface Group.  If line group ID is a T1,
the associated DS1 channel number is 1.
          
GR-303-CORE R12-508 [1377] The RDT is limited to 
a maximum of 28 DS1s per IG and each IG can 
support up to a maximum of 2048 two-wire 
terminations toward the customer's premises.
          
Once a primary or secondary DS1 is provisioned for an 
IG it cannot be modified or deleted.

The GR-303 CRV Table.
          
The GR-303-CORE interface uses the Call Reference 
Value (CRV) in its Timeslot Management Channel 
(TMC) to dynamically assign DS0s to access 
circuits on a call-by-call basis; i.e., if an 
access circuit is not assigned a CRV, it will 
never be assigned a DS0 between the IDT and IG.
          
The maximum number of entries is specified by the 
maximum number of  subscribers or CRVs for the 
Interface Group, which is 2048.  Each Interface 
Group is associated with an igCrvTable indexed 
by (shelf, slot, IG name, CRV).
          
GR-303-CORE R12-508 [1377] The RDT is limited to
