In the Matter of
Ameritech Operating Companies Transmittal No. 892 
Tariff F.C.C. No. 2
ORDER 
Adopted: August 14,1995; Released: August 15,1995
By the Chief, Tariff Division, Common Carrier Bureau:
1. On June 20, 1995, Ameritech Operating Companies 
(Ameritech) filed Transmittal No. 892 to introduce an 
optional feature. Carrier Identification Parameter (CIP), as 
part of the services offered under its Tariff F.C.C. No. 2. 
Transmittal No. 892 is scheduled to become effective on 
August 18, 1995.
2. Ameritech explains that in the signalling system seven 
(SS7) environment, the Carrier Identification Code (CIC) 
currently is generated at Ameritech end offices and trans 
mitted to the Ameritech access tandem or to an alternate 
provider's access tandem. The parameter containing the 
CIC code is subsequently stripped at the access tandem and 
the CIC is not sent to the customer. Ameritech explains 
that, by contrast, CIP will allow the transmission .of the 
CIC to the customer. CIP will be deployed at both end 
offices and tandem offices. Ameritech states that CIP will 
facilitate the growth of competition in tandem switching 
services and will enable interexchange carriers (IXCs) to 
meet branding needs and offer new services, such as cus 
tomized routing, traffic analysis, and traffic prioritization.1
3. Ameritech proposes recurring and nonrecurring 
charges for CIP on a per trunk group basis. Ameritech 
states that the recurring charges recover the costs associated 
with the purchase and the loading of the right-to-use soft 
ware to equip end offices and tandem offices with the CIP 
functionality. Ameritech states that the nonrecurring 
charges recover the provisioning costs associated with 
equipping the customer's trunk groups with the option, as 
well as the costs required to modify Ameritech's billing 
system.2
4. Ameritech claims that the provision of CIP as an 
optional feature is a service authorized by the Commis 
sion's Tandem Switching Order.3 Ameritech states that the 
Tandem Switching Order requires it to provide signaling 
information from equal access end offices to third parties. 
Ameritech claims that this filing is consistent with the 
Commission's affirmation that broader interconnection re 
quirements to facilitate access competition are in the pub 
lic interest.4
5. On July 5, 1995, MCI Telecommunications 
Corporation (MCI) filed a petition to suspend and investi 
gate Ameritech Transmittal No. 892. MCI argues that CIP 
should be a non-rated feature because it is a network 
upgrade -- similar to SS7.5 MCI states that in the 800 Access 
Order, the Commission decided that SS7 represents a gen 
eral network upgrade, the core costs of which should be 
borne by all network users.6 MCI then asserts that 
Ameritech should not be able to charge for CIP because it 
is an SS7-based feature.7 MCI also argues that there is no 
difference between CIP and the Commission's recent de 
cision to require carriers to pass Calling Party Number 
(CPN) information to interconnecting carriers free of 
charge.8 Assuming arguendo that it is reasonable to charge 
for CIP, says MCI, CIP should be available on a trunk- 
by-trunk, as opposed to a per trunk group, basis to allow 
MCI to buy only the amount of CIP capacity needed. MCI 
claims that such unbundled pricing is in the public inter 
est."
6. On July 5, 1995, Allnet Communication Services, Inc. 
(Allnet) filed a petition to reject Ameritech Transmittal 
No. 892. Allnet claims that in the recent Caller ID Order, 
the Commission decided that CPN should be passed from 
carrier to carrier at no charge because it is an intrinsic part 
of SS7 call set up and because the cost for transporting the 
CPN parameter for carriers equipped with call set up is de 
minimus. 10 Allnet also claims that in the Caller ID Order, 
the Commission found that installation of SS7 and related 
features is a general network upgrade and the cost of this 
upgrade should be borne by all network users. Allnet then 
argues that, just like CPN, CIP is an intrinsic part of the 
SS7 call set up process and no additional costs are required 
to forward CIP to the IXC. Allnet therefore reasons that, 
consistent with the Commission's previous findings, CIP 
should be provided at no charge."
7. On July 17, 1995, Ameritech filed a reply to MCI's 
and Allnet's petitions. Ameritech argues that MCI and 
Allnet cite "completely out of context" Commission state 
ments on the topic of SS7 costs being treated as a "general 
network upgrade." Ameritech notes that in the same pas 
sage, the Commission states that it will "treat as the costs of 
providing data base access service only those costs that are

incurred specifically for the implementation and operation 
of the data base system." 12 Ameritech then argues that in 
the instant transmittal, the recurring charges cover only the 
incremental costs associated with the purchase and loading 
of the right-to-use software to equip end offices and tandem 
offices with the CIP functionality itself. Ameritech argues 
(hat no portion of the cost recovery associated with this 
rate element can be considered a "general network up 
grade;" rather, this element recovers only those costs which 
are incurred specifically for the implementation and opera 
tion of the CIP functionality. 13 Finally, Ameritech explains 
that it adopted a per trunk group basis for the rate struc 
ture of CIP because it is the industry standard for this 
feature. 14
8. The Tariff Division has reviewed Ameritech's Trans 
mittal No. 892 and the related pleadings. We conclude that 
no compelling argument has been presented that this tariff 
is patently unlawful so as to warrant rejection or that it 
raises substantial questions of lawfulness that warrant inves 
tigation at this time.
9. Accordingly, IT IS ORDERED that the petition to 
suspend and investigate Ameritech Tariff F.C.C. No. 2. 
Transmittal No. 892, filed by MCI Telecommunications 
Corporation, IS DENIED.
10. IT IS FURTHER ORDERED that the petition to 
reject Ameritech Tariff F.C.C. No. 2, Transmittal No. 892. 
filed by Allnet Communication Services, Inc., IS DENIED.
