Phantom/Virtual Superloops
Phantom Superloops are used for phantom DN's. Phantom DN's are used as an alternative to dummy (secondary) ACD queues, and typically route calls to Meridian Mail or Call Pilot dialable services (via the VSDN or SDN table). Phantom DN's exist only in software, there's no hardware.
"Virtual DN's" are similar, they also exist only in software, but are used for IP sets and trunks.
- Phantom loops are for 500 type phones
- Virtual loops are for IP phones and trunks
Note: A superloop cannot mix both phantom and virtual units, it must be one or the other.

Virtual TN's (IP phones):
N & V superloops behave just like physical superloops, but without hardware.
Virtual TN's for IP phones/trunks follow the same rules as any other TN:
| Loop | Shelf | Card | Unit |
|---|---|---|---|
| Multiples of 4 | 0 or 1 | 0 → 15 | 0 → 31 |
So, 32 units per card, 16 cards per shelf, 2 shelves per superloop = 1024 TN's (IP phones) per Virtual Superloop!
Note: Its recommended to program Phantom and Virtual loops from the highest loop number backward to prevent conflicts if the system is ever expanded later. Virtual loops (for IP Phones) are typically built from 252 down.
Option 11C Phantom Loops
Option 11C Loops are a little different to those of large systems. On Opt 11C, Rls 23.55, loop number range is 64-80 in multiples of 4 - corrisponding to slots 41-60. With Rls 24+, the Opt 11C range is increased to 96-112 in multiples of 4 - corresponding to slots 61-80. Use the following tables to figure out the Loop and associated TN values for Option 11C switches.
Opt 11C Phantom Loops & associated TNs
| Loop | Associated Phantom Cards | Units | |||
|---|---|---|---|---|---|
| 64 | 41 | 42 | 43 | 44 | 0-15 |
| 68 | 45 | 46 | 47 | 48 | 0-15 |
| 72 | 49 | 50 | 51 | 52 | 0-15 |
| 76 | 53 | 54 | 55 | 56 | 0-15 |
| 80 | 57 | 58 | 59 | 60 | 0-15 |
Opt 11C with Line side expansion (LSE)
| Loop | Associated Phantom Cards | Units | |||
|---|---|---|---|---|---|
| 96 | 61 | 62 | 63 | 64 | 0-15 |
| 100 | 65 | 66 | 67 | 68 | 0-15 |
| 104 | 69 | 70 | 71 | 72 | 0-15 |
| 108 | 73 | 74 | 75 | 76 | 0-15 |
| 112 | 77 | 78 | 79 | 80 | 0-15 |
Option 11C with Line Side Expansion (LSE): X11 Release 24 software added 32 to the loop and 20 to the Terminal Numbers (just to confuse you).
