Speed Form
The following table gives a brief description of the fields contained in the Speed Form.
Name |
The name of this speed |
SubChannelFrom |
The lowest number this Speed’s sub channel starts from |
SubChannelTo |
The highest number this Speed’s sub channel ends with |
SpeedType |
Short descriptor for this kind of speed i.e., PVC, DynamicVC, IP |
CircuitTypeOption |
Shows the directional aspect of circuits using this speed. Options are BI, UNI, BI or UNI |
ShowSubCircuitMenu |
Right click functionality on a circuit will show sub circuit menu See section below called ShowSubCircuitMenu & ShowCircuitAddNewMenu features
Warning: this option affects overall performance, as the selection of circuits in IMS of this speed, will cause the server to pre-process and retrieve all sub circuits prior to opening the required circuit. Use according to requirements only. |
ShowCircuitAddNewMenu |
Right click functionality on a circuit will allow adding a new circuit on one of the free channels See section below called ShowSubCircuitMenu & ShowCircuitAddNewMenu features |
ChannelView |
Creates predefined channels on: 2MB (32 timeslots), NORMAL (no channelisation – default), VC4 (KML notation), VC4_I (International – allows for T1 access) |
KBits |
Kilobits of payload capacity for this speed. No inherent capacity calculation performed on this field. Potential to write reports that make use of this field. |
LayoutType |
Options for circuits: Multiple, Normal, VCGroup, VLAN. Multiple setting enables a Circuit (service) to: a.Be associated with more than one circuit for High Redundancy b.Be a Point to Multipoint connection – one source many endpoints VCGroup setting is used for Link Aggregation and Hub and Spoke type connections, i.e., Ethernet over Sonet/SDH VLAN setting is deprecated. Normal is the recommended default setting if none of the above are required. |
E2ECheck |
For circuits when their status’ are set to IS, IMS will first endeavour to locate a consistent sequence of relevant links from their A to Z route across the network |
DefaultServiceParts |
Optional field that serves to auto populate a given value, from a dropdown list, every time a new circuit is created |
DefaultProductId |
Optional field that serves to auto populate a given value, from a dropdown list, every time a new circuit is created |
DefaultCustomerId |
Optional field that serves to auto populate a given value, from a dropdown list, every time a new circuit is created |
DefaultVendor |
Optional field that serves to auto populate a given value, from a dropdown list, every time a new circuit is created |
CircuitNameTemplate |
If left blank, the IMS’ standard circuit naming convention is implemented when a circuit is created- The default naming template is: [SITEA.NAME]-[SITEB.NAME]-SPEED.NAME-[ [NUM:3:1:1:10000:0:0:0:0](CUSTOMER.NAME) All circuit names must be unique. |
CableConnectNameTemplate |
Naming convention setup for Cable type connections - Applied using the right mouse option on ports during a Cable Connect activity - typically on DDF/ODF ports. Refer to the section in IMS Basics User Guide called Naming Conventions for more information - Sub sections : Speed and Cable Connect Name Template. |
ExtraInfo |
User defined extra information field for this speed. |
DrawSubCircuit |
Used in conjunction with the Open Circuit Path feature in the CircuitForm Actions button bar. It will also draw the subcircuits contained in the opened carrier circuit. |
UseSubCapacity |
Network Map feature. Enables the display of capacity usage on a carrier circuit – see the screenshots below in section UseSubCapacity feature. |
OloSpeedAllowed |
Allows for association between a circuit and an OLO circuit of different speeds i.e., a circuit of speed 1GBE can be associated with a 500MB OLO circuit. Ordinarily IMS looks for similarity between associated circuit speeds. |
AEndMandatory |
Defines if a circuit using this speed must have a SiteA side component |
ZEndMandatory |
Defines if a circuit using this speed must have a SiteB side component |
MultiPoint |
Will allow for a circuit name to represent more than one circuit made up of various circuits, one for each multi endpoint. |
WizardUsable |
Feature not functional at present |
Optical |
This enables IMS to directly connect two ports together with a cable circuit. Ordinarily IMS first checks for a carrier circuit to be available between the A and Z end ports. |
Test |
If enabled, IMS performs a validation on a new circuit with this speed to ensure that the circuit’s field called Tested is set to YES before saving it. If the field’s value is NO, then an error message warns the user (lower right corner of the Circuit Form) |
IsGeo |
If enabled, new circuits will contain latitude and longitude coordinates, useful for when using the street mapping feature in Network Map. |
ShowVlanId |
If enabled, when a new circuit is created, a VLAN ID must be entered in the VLanId field |
GraphicalX |
Column number definition for channels displayed with the Open Subgraphical feature which can be found in the CircuitForm Actions button bar |
GraphicalY |
Row number definition for channels displayed with the Open Subgraphical feature which can be found in the CircuitForm Actions button bar |
Lower Tabs Panel
The Speed form can contain tabs of information in the lower form panel, relating to the Speed opened in the Speed form.
Sub Layer Tab
The following information refers to this Speed's sub layer details. There can be more than 1 related Sub Layer Speeds.
